Hello, I am planning to take the CSET MATH test. I understand that only certain models of graphing calculator is allowed for subtest II. My question is if the calculator is really needed. Can I take the test without one? For those who have taken the test, did you use the calculator for things other than number crunch during your test? I am trying to see if I can get away by not spending $100 to buy a new calculator. Thanks in advance for your help.
