How many colleges should you apply to?

This depends. Any more than 10 is too much and anything below 6 is too little. You have to keep your options open but having way too many will be daunting when you have to decide among so many acceptances while having too little will be incredibly difficult to handle especially if you don't have many options to choose from. Financial Aid is also something that students need to consider. The more the student needs it, the more schools they should apply to. But again anything more than 10 is too much!
