If you're not sure whether or not you'll be accepted to any college at all, here's something that might encourage you. Go to the College Board's website and use their "College MatchMaker" function. Select "Four Year" colleges and then, under "Admissions" select "More than 75% accepted."
You'll find over 400 colleges (roughly 20% of the total number of four-year colleges in the United States) that take nearly everyone who applies.
From there, you can limit the search to particular states, number of students that attend, or what majors are offered. But start with the broad list and then start eliminating.
And you might be interested in one of my old posts about how B and C students can still show their potential to colleges.
There's probably a college out there for you if you want to go.
