I am a sophomore in high school and I will be taking AP Calculus soon. This class also has a bit of Trigonometry. I have tried various mathematical problems, ranging from the most complex, to the simplest of them all. After doing so, I learned that this calculator is very efficient and fast in solving practically any math problem the average high schooler will see. In addition to its efficiency, it allows for multiple applications which you can easily download from a computer. I have to admit, though, that the buttons and controls may be a bit confusing to someone new to the TI calculator series. However, with a bit of practice and reading, this calculator will be simple. The TI-84 plus is truly a good option for a student in need of a graphing calculator, but isn't wealthy enough to afford those flashy, color calculators.
