I have an exam, and as a requirement they reset all of your calculators by pushing the little button in the back. I have a program there that has all the formulas, and I would like to have it during the exam, What way could i un-delete a file, hide the file, or simulatate a reset when the button is pressed. I would like no hardware change

[betoe]

I think you cant, in the AFX you can save your programs on the flash memory, but if you have a CFX... you cand to anything, only keep them on your PC and dont use them on the exam.

[casiokingdom]

yeah, sorry, you can't. my school allows programs to be taken in.

[genesis]

??? Why does everyone say that? When I push the button, it just goes to the Memory menu... it doesn't just reset instantly. If its just a minor school thing, you could try fake reset programs, using other areas of the calc etc. but if its an exam, I wouldn't try...

[huhn_m]

it asks you wether you want to reset and I suppose the teachers simply press YES

[Bob Vila]

you could just get one of the fake reset programs, run it and show it to your teacher

[huhn_m]

I wouldn't do this since they are not 100% real on CFX
(only possible on AFX) and it can be easily noticed.

This qualifys as cheating and could lead to your disqualification!!!

[betoe]

aaahhh third world uni's.

Here i can use all i want on my graphic calculator. Teachers seems to be amazed watching me using the classpad. A lot of them think its a PDA.

[CrimsonCasio]

seems there aree good aspects to living there

Exactly... but isn't it possible to make a fake reset program/draw memory/picture? They don't pay that much attention!

[Bob Vila]

i'm taking the ACT next saturday so i will probably have to reset my calc for that

[Bob Vila]

ha! they didnt even check to see what kind of calc you had! i could have "borrowed" qwerty's classpad and they wouldnt have even noticed (maybe )

Nope. We are better than you because we can solve these things
without calculators! ALL OF THEM!

but ... well.. you're right it sucks.
And the best is. The new classes that get in form 8 the next year will
get a cas calculator. I heared that the teachers
were just testing some kind of TI calc with cas on it.
Maybe I sould recommend them the classpad?

[CrimsonCasio]

do it, give casio a free plug

[betoe]

Nope. We are better than you because we can solve these things

Well i did reference to this coz here in my city (dunno on the big cities) nobody use graphic calculators, and a lot of people think that i'm playing tetris (when i'm using my AFX) or my classpad is a PDA. In my uni i had saw:
1- teacher with graphics calculators, TI and HP (he know a lot, very good teacher)
1- A guy with a TI-89 but he has died
1- A friend in his first uni year with a classpad
2- AFX of 2 guys of my classroom
1- CFX of another friend
1- TI Voyage of a guy in him first uni year.

Some of this guys bought their calculators when they saw me with my AFX.

[Andy.Davies]

well there are these in my college:

1 - AFX user (me)
1 - TI 89 (my best friend, tho he only bought the TI cos it was ?25)
1 - old Casio Graphic (the maths teacher, he knows nothing bout his calc)

[Mr_Sparkle]

hey

im sorry to say but u cant really do much
the same thing happened to me last year
and i had all these wiked games on
by the way i have a CFX-9850GB PLUS

so sorry mate but i think ur screwed

do u have a friend or sumfing u could borrow 1 off for the exam and swap them over or sumfing??

ne way good luck with ur exam

i have 2 tomorrow
and ive got a broken thumb!!

[alias4399]

Wait, i just thought of something. I remember that there are slightly advanced techniques which allow you to have text AND graph things (ie have graph mode + text mode) at the same time! It wasn't really that difficult, actually. (The reset screen has G + T modes)

Another thing, couldn't you send a screenshot of the reset screen to your PC via the calc and save it as a picture? Then just RclPict and your away! You could make a program to display the pic, then wait for Yes and display "Memory Cleared" EXACTLY as it is on the real reset menu.

Still, if your busted, your busted.

[Scratty]

Ok, just my 5 cents on this matter.
I will talk from my own experience here.
I think that if it is pre-university (highschool - college or so) then you might be able to negotiate with your teacher about the programs. I succeded to keep most of my programs by claiming that I had made them myself and arguing that I already know the stuff that I have made programs for or else I wouldn't be able to code them up and then I briefly explained what the programs did and showed them to the teacher. That worked fine.

However at the university (at least my university) first of all, graphing calculators are more ore less banned (some courses make exceptions) and secondly, there are not teachers that supervise the exam. They just pop up occcasionally to answer questions. Thirdly, the tasks on the exam thesis are constructed so you can answer them without a calculator. If it says you can have a calculator, they almost alway refer to specific calculator models that can't be programmed.

If you have a calculator that contains a lot of good programs you can't download to your PC in time for the exam, then ask a fellow classmate if you can borrow his calculator. I've done that several times throughout my studies (often due to misplacing my own (accepted) calculator).

Faking a reset is daring and extremely foolish. If it is a small class or if the teacher supervises the exam, then you will lose his trust forever (in the best case). On a large university you will be reported to a disciplin council and risk being expelled from the school for a year or so, and that might mean loss of fundings and in the worst case you might end up on the street.

So ask a friend, carefully negotiate with your teacher or backup (write down/upload to PC) the programs you have should your previous options fail. That is my advice to you.


Now, good luck on that exam!!

[LordNPS]

Or you could buy an 9860 SD, and then, insert the memory card in the middle of the exam

The consequences can be very nefast indeed (thanks for the dramatization scratty )
However the consequences of using something and not getting caught are pretty good themselves, now, it's up to you to decide.

Except if you are in portugal since most teachers can't recognize a SD card, they can barely use the calculator for arithmetic purposes... after much trial and error.

Yet they are kindly tolerant to the use of graphing calculators... my math teacher once let a student use his laptop as calculator...

If you are in australia, you probably won't have acess to an 9860 SD only 9860 AU

In Brazil you are more likely not to recognize a SD card yourself, nevermind your teachers...

In china, vietnam and outstrikes... you could get military execution for copying in an exam, my guess: it's not worth it.

In the states, there are probably 300 difrent laws in each state that protect sudents who want to copy or cheat in their maths tests, so nevermind avoiding detection.

In japan you are most likely to achieve a better performance using your own head rather than a calculator, as you have 5- 6 times the processing capability of a calculator...

In the rest of the world, I don't really care


Now seriously, if you are not copying then show your teacher what each program does and how harmless they are... you may even resort into asking him/her to lend you his/her calculator
Else, you can atempt one of those programs and hope your teacher swallows the whole thing.

[The_AFX_Master]

Fuc*** Sh** !!!! ROFL!!!! I'm laughing..so...so...hahahahaha!!!!! . funny post Lord!

In my country, teachers does'nt believe that a calculator of any brand (exept HP's) can be programmed.

[kucalc]

Using a fx-9860 SD and putting in a memory card in the middle of the exam is nice. At my school, I had a classmate who wrote down forumlas on the back of his black TI-83 (eveyone at my school uses TI's except me and my friend) using a gray pen. Its hardly noticeable unless you look really close at it. Anyway, he through quizzes and tests by doing that and never got caught.

[Scratty]

Hmm... about the SD card, that is quite disturbing. On the other hand, I'm not particularly suprised.

Personally I think graphing calculators should be banned in class (yes, you heard me right). Sure they are good for understanding curves, tangents, secants and all that stuff. But I wonder if they don't spoil more than help in the end. A common handicap that can occur after some time of diligent calculator usage is that you eventually calculate the simplest arithmetics you can imagine without using your brain (been there). I think there's some true behind it when people call calculators a "brain prosthesis" . After all, teaching should encourage students to use their brains rather than learning how to avoid using it. From what I've learned, detaching from using calculators in the university is hard for some freshmen.

And concerning cheating, think of it this way: Would you like it when you have nailed the exam by studying real hard and you find out that a classmate has cheated on the exam and not has understood a thing of what it was about? How would you react to that? Another way you can think on the matter is that if you cheat without getting caught throughout your studies, wouldn't it be scary when you get a job and a salory they think you're worth, when you know that you can't peform the job that is required of you?

Now I sound like an uncool old dude with a beard and a kane (ok, let go for the beard, but I have no kane just yet ) wagging his finger. Everyone hates moral lectures. What I guess I'm trying to say is that follow your heart and please don't let my moral lecturing intimidate you from putting your calculator at good use.
Sorry for ruining the good mode here .

whee... I hate long posts, and I've just written one myself

[calculor]

I don't see why people say you are screwed. I can think of two methods which will involve a supervisor appearing to reset your calculator while you still retain your programs. Both require some simple electronics skills (If you can hold a pencil, you can hold a soldering iron, so you can do this).

Firstly: You could do the modification here:

http://www.eow.ath.c...d=ram9850gbplus

Which will enable an extra 64K memory bank. (You'll need to borrow a PC-Calc cable to back everything up before you pull it apart) The two banks are seperate, and are switched between with a switch that you can hide in the backup battery area. Upload the programs back on to your calculator, switch off the calculator, switch memory banks, upload again, and when you go into your exam hand it over and let them do their thing. Once you take a seat, you just have to open up the battery compartment, flick the switch, and you will be able to use all the programs in the memory that wasn't erased.

[A cool extra touch would be to desolder the contacts for the data port, hot glue the data port back in place, then wire the two wires that would otherwise go to a hidden switch to the contacts on the jack, then superglue tin foil around the circumference of the rubber plug that goes into it. Once you sit down, just pull out the plug and drop it in your shit pocket. That's much more smooth than opening the batt. compartment!]

Another option:

You could write a program that clears the screen, and then goes into a loop testing for, say, F5. The screen will be blank (except for the thinking square) which the supervisor probably wont even notice after going through so many calculators. You then make the program act like the reset screen. I don't know how to do it but others have. The trick is, you have to open up your calculator, cut the traces around the reset button, and rewire them up to the contacts for F5. Before you walk in, execute the program and hand it over. When they press reset it will register as F5 to the calc, and the reset screen will come up. This is pretty pointless though, since if you are going to open up the calculator you may as well get an extra 64K of memory by doing the above modification.

Thanks


now seriously scratty If you were still in school you would realize that cheating is most times the best option.
Because while you are copying the formulas etx to your calc you are momorizing them too...

And yes, it was quite a lecture thank you very much... I'll buy you a cane and lend you one of my pipes for that

[Scratty]

Sure... if you don't need the kane yourself, I gladly accept ur offer . However concerning the pipe, I must kindly refuse.

Yeah, I almost regret I said all that... but I felt there might be some guys out there who should here me out in this matter.
I would really hate to hear of talented calculator programmers that get caught due to cheating. The society needs good programmers!

And... sorry to say, IMHO you're quite wrong about cheating. Learning by programming stuff does by no way justify cheating, I might understand people think student allowance problems justifies cheating, but not learning, not by a long shot. Cheating is unfair and immoral, period.

Furthermore, it is IMHO even wrong to memorize formulas. You should learn to understand them, not memorize them . If you understand them, then you won't need to memorize!

[LordNPS]

And... sorry to say, IMHO you're quite wrong about cheating. Learning by programming stuff does by no way legitimize cheating, I might understand people think student allowance problems legitimizes cheating, but not learning, not by a long shot. Cheating is unfair and immoral, period. motz.gif smile.gif

Cheating is considered part of the american way of life.
Not cheating when you can is refusing using the intelligence and smartness god gave you...It is natural to atempt to improve your performance no matter the cost. I think it is your duty to yourself to cheat whenever you can
(actually I never cheated, I get a 20/20 at maths without studying or copying)

[Scratty]

Hmm... now that's an interresting point of view. You sure got a point there .
There are smart cheaters and stupid cheaters. Smart cheaters get smarter whereas stupid cheaters don't. Unfortunately, I think there's a majority of the latter category :/.

In France, the limits for a calc in High School (baccalaur?at) are as follow :

No power plug.
No printer.
Max size : 21 cm by 15 cm (that is huge for a calc). If the calc can be folded, it is the folded size that counts.

That's it.

Of course no transfer of data between 2 calcs during the test. No exchange of calc between students during the test.

The calc is not reset (I heard it is because your programs are considered as intellectual properties). Nothing in the memory has to be deleted. The content of the calc does not have to be controled.

However, the test is made according to this. You can't write just an answer, you have to detail everything. And the test is not multiple choice.

If for any subject the calc is forbidden, it has to be specified on the test sheet.
It is usually specified for the philisophy exam...

[Scratty]

Wow, that's generous.
To tell the truth however, I can't exactly recall how it was back in high-school for my part.

The calc is not reset (I heard it is because your programs are considered as intellectual properties).

Oh. Well, then you could just as well bring a handwritten sheet of paper to the exam/test .

However, the test is made according to this. You can't write just an answer, you have to detail everything. And the test is not multiple choice.

If for any subject the calc is forbidden, it has to be specified on the test sheet.

That's how it is in my university as well. Either you're allowed to have a university-approved calculator, any calculator (very rare) or no calculator at all. Usually, when you're allowed to bring any calculator, you're also allowed to bring any books, papers or whatever you feel you need. These test are the hardest. So despite what one might think, no restrictions on an exam is not easier than those with restriction. back when I studied, I used to be very delighted when you had a course where on the exam you were only allowed to have a pen and a rubber. Those are the easiest exams! (generally speaking of course)

Hah! Funny note about the philosofy exams .

[LordNPS]

It is usually specified for the philisophy exam... biggrin.gif

Well not in my school, in phillosophy when the test subject was "logic" you were allowed to bring you graphing calculator(which is required in my school, really required, and not just any calc, it has to be a good Casio or Ti graphing calc no 7400's for us it has got to be above CFX 9750 or above Ti 84 (even though my math book describes the calc procedures using a Ti83 and Ti84 and Ti83 are alike) , thats portugal my friends ) to calculate simple fractions rquiered in that subject, in the analitical logic part.

[kucalc]

Of course no transfer of data between 2 calcs during the test. No exchange of calc between students during the test.

This gives me an idea. What about RF transmission through calculators? You plug the device in your 2.5mm socket in the calc and go to the LINK menu and just transfer the data. The device would be transceiver so it can receive and transmit. Also, with the device you could do multiplayer and play against other people on your calc! I think I have seen this done before, but I tried googling it and can't find it..........

At my old school, Casio graphing calculators were forbidden. They were considered to advanced. TI were were accepted because they lacked features the Casio had:

Conics
Equation Solver: Simultaneous, Polynomials and equations in general
Financial and Buisness functions
An easy way to use matrices

The equation solving capabilities is the probably the biggest feature teachers hated at my school. We had this math time test once. There was 50 quadratic equation problems and we were given one hour to finish it. With my Casio, I just type in the equation and it would give me the answers. I was able to complete the test in less than 10 minutes and got every single answer correct. Everyone else, who was using TI, did not do so well on the test and half of them got a C or lower. However, the teacher got suspicious and the whole entire class grouped up against me and said a Casio was too powerful. The next day I wasn't allowed to use Casio and was told to go get a TI. I never did get a TI and I never again used a calculator again during my stay at that school. I still passed that class with a A.

Nevermind, I found what I was looking for here: http://www.ticalc.or.../text/hardware/

Scroll down the page and look for Radio Transfer Link Plans which was done by Michael Jan. Once I get some money to buy some parts, I'll try to adapt it for Casio calculators and I'll share it with everyone on UCF.

This is not possible in France, where you have to detail everything.
You have to solve your equation on paper, not just write the answer.

What's the use of a calculator, then ? Check your answer, be sure the graph you drew on paper is coherent etc.

[kucalc]

Well then, I wish that when you to the EQUA and type in a equation it would show the steps to how it came to a numerical conclusion. Then you could just copy down the steps onto the test and voila! It would take a lot of code and programming for Casio to do this though........

I hope you are being sarcastic, as that is exactly what tutor, with CAS does.
AFX and classpad can do it.
