Also you don’t need to visit really. You can use google and brochures to do those essays. I did.
Also if you qualify look up college flyins. Basically a college will pay for you to visit for free. Typically you have to write a small essay, submit grades and scores, but it’s an amazing way to look at schools. Most apps are due the summer before senior year, so really start looking at if your colleges have them. Typically Liberal arts colleges have them, and not large universities.
