The display works but it's not pulling the information from the scores.txt so I don't know if it's not pulling from the right place or a formatting problem or something.

for (category=0; category <= maxCategory; category++)

aren't you resetting the value of category to 0

also in your main() you have a student array but are you actually using and filling the array right?
