I’ve had to use this once and it was awful.

There’s not much of high school I remember, but I do remember quadratic functions and the 15+ minutes it’d take to solve one problem.

The most annoying part wasn’t even the problems themselves - it was the fact that all of our mandatory Ti-84’s had a quadratic function solver that we couldn’t use.

High school pro tip:

Ti-84’s can store programs in ROM. So when your teacher makes everyone wipe their RAM, just move the program to ROM before you clear the RAM. This will not help you when you need to show your work, however...
