Just to throw some advice in here,
Taking it to college is one thing, carrying it is another. I have carried many knives to many different colleges in my struggling years throughout Texas. Carrying fixed blades around a campus irks a lot of people, too many sheeple. Size isn't really the problem. Hell my psychology teacher carried a cold steel folding 5" blade and another 5" blade with it since he couldn't carry his side arm onto campus. (He was proficient in knife defense as he trained frequently). That aside tho, in all honesty I would save up for a good folder to use for utility purposes if you intend to carry a knife around.
For the price you can get a folding griptilian for $60 which is an extreme knife for the money and if you pull it out to cut something you won't get a bunch of people squirming away from you or running to the nearest campus officer.
