I would buy a calculator to use on the test because you will need it for calculations like molar mass and dimensional analysis calculations which can be tricky and time consuming to do by hand. Calculators were not provided during my test, but it might be worth it to double check with your TA.
I like my calculator because you can scroll and use the last answer to solve another problem! So if you calculate the molar mass of a compound you don't have to re type it! It's the Ti-30xs! I really recommend it!
