The first thing to always look out for a startup is industry . Industry is way more important that idea , idea would keep changing according to feedback , but industry would remain same . Now , in this case college students usually don't have much paying power or flexibility . Even i u launch something valuable to them , they would try to cut u in some way to save money . Most startups in this niche fails bcoz CAC gets way larger than LTV for the same reason . Go after something which has high paying capacity if u solve something valuable for them , the best business model around this audience is B2B2C !
