Exam Approval Matters
If I am buying a calculator for school, I always confirm that it is allowed for my exams. The TI-83 Plus is commonly accepted in many classrooms and standardized tests, but I still verify the rules for my specific course or test. This saves me from buying a calculator I cannot use when it matters most.
My Tips for Getting the Best Value
I usually compare prices from a few sellers before making a decision. If the calculator is used, I look for a fair price based on condition and included accessories.
