I remember for Maths, Further Maths and Computing A-Levels typing in mini programs for everything into my TI-85, from stats to bubble sort or curvature. It took so long typing that on a numerical keypad I could remember everything and no longer needed it. Still, a good exercise in basic programming and not unlike remembering from a flashcard deck. Four years later in banking, I discovered the entire industry does the same, but in Excel. Enjoy your studies!
