Exam 2 CAS Skills Trainer

Focused on Exam 2 skill types

Practise the exact CAS moves students need, without using exam questions.

Exam habit checklist

I define variables before typing a CAS command. I know when to keep an exact answer and when to approximate. I copy the CAS result into a clear mathematical sentence. I substitute or estimate to check whether the answer makes sense.
