For those who had done quite a few VCAA exam 2's, I want to ask did you notice any questions that whole freeze your calculator?
It happened to me once from doing an exam paper from another company and it means that I have to reset my calculator and lose all the stored functions.

Just wondering, would VCAA ensure the equations and questions that require calculator solving won't be too long to solve so that the calculator won't freeze?

Suggestion: don't reset, just pull the batteries out, everything should be kept and the calculation will stop :)

I think usually those questions are made to be attempted differently, eg. by hand etc.

If it freezes, just press the ON button to stop whatever you are doing.
If you are finding that solving is taking too long, try to use nSolve with a specified domain, or sketch the graphs and solve via intersection of two curves.

If you are using a classpad, in the bottom right hand corner of the screen click the "esc" button if you ever want to stop the calculator from loading

Or you can press clear.

But it's pointless, you don't get the answer.

I can't stand the CAS calculators. Sure, they have more controls than the space shuttle and can help process the most difficult of questions as a "get out of jail free" card, but they just feel WAY too cumbersome.

I strongly prefer Exam 1 as I prefer to "pack light" with just a pencil or two, an eraser, a sharpener and my brainpower.

Yes, CAS is an abomination. It produces so many issues... peoples calcs not working, different calcs working differently. The calc costs money when education is free, yet is a necessity... etc.

Yea the thing is I *think* VCAA would ensure that the calc won't take too long to solve the questions so that hopefully no one freaks out from calculator freeze
