I think it's wrong to think of Exam 2 as a "calculator based exam". It's simply a maths exam in which you are allowed to use calculators. A major issue I have with Methods CAS is that it allows students to blindly use the calculator as if it is the only way to do a question. It strips away a great portion of the mathematics by letting a calculator do it. Instead of just ignoring the question because your calculator couldn't do it, you should have tried to gain half the marks for that question by finding the derivative by hand and having it equal to 0. At least then you've demonstrated that you understand what the question is asking.
"what about those who didnt have calculator problems but simply didn't attempt it because they didn't know how to?"
To quote VCAA: "The VCAA calculated an estimated score for question 3(e) for all students based on their individual performance on the rest of the examination."
The key word here is individual. If a student doesn't know how to find a maximum then it's likely to have shown in the rest of their paper.

Very well said. I would +karma you but I'm clearly too noob.

There's no point in finding excuses especially as VCAA has come up with a rather fair solution. I believe that I got that question correct (I used a TI) and I can live with this remedy and in fact, I applaud VCAA for handling it in such a manner.
