I'm not a big fan of math...and most of the stuff I had to study in my prep courses for the CSP exam was math I haven't done since college....about 10 years. So this calculator was the required one for the exam...but you can't bring it into the test, you need to use the emulator on the computer. So you need this to prepare and get yourself ready. I also never realized these calculators can give you variable stats.....it has now been 15 years since I had to do long math for Mean, Median, Mode, SD, etc.
