<p>You should absolutely apply. College admissions is more about what you’re capable of doing going forward rather than where you come from. It sounds like you’re a good, hard working kid who’s gotten his (her?) act together. Trends in grades matter a great deal and to go from a 2.5 to a 4.1 in a lousy high school is no small feat. Good luck! Also be sure to look at programs like Questbridge (?) which may help you in applying to college.</p>
