As noted above it is fine to apply to a few reach schools but it is important to have match and safety schools that appear affordable (run net price calculator) and that you would be excited to attend. There are tons of amazing colleges and universities out there! And IMO you should absolutely look at the public college options in your homes state as they will be cheaper than private schools with no aid.
