Slight differences between the courses too. For example, CAS kids do some stuff on matrices, whilst normal methods people won't.

In CAS there are a number of different things:
-The calculator- the ti 89 is used instead of the normal 84 or 83, the ti 89 is normally more powerful and has more alot more features.
- Matrices are included in the cas study design. They are mainly used for probablity questions, and there are normally a few questions on these in the exam, including an extended response question.
- CAS is normally scaled higher than methods (about 1 point extra)
- There arent many schools that do CAS methods, but I think in 2009 or 2010, the CAS course will be compulsory
-The first exam for both subjects are the same while exam 2 for methods CAS might have different extended response and multiple choice questions

thats about all I can remember.

I also find the methods CAS papers slightly harder than the methods ones.

Yes the use of matrices in CAS is a significant difference. (In transformations and in probability)
Also applying integration to find the 'average value of a function.' (1 multiple choice question on Exam 2)
The CAS exam often includes some questions involving pronumerals (a,b,c) rather than 'normal' numbers- these are usually desgined to be non-calculator questions which test understanding of concepts.

I find it funny when they try to do this in spesh considering CAS can actually handle pronumerals? I've had a number of times where you can still one-step these questions on a CAS regardless.
