<p>Wherever you go, make sure you find out what resources are available to help you with time management and study skills. I also came from a weak high school - I coasted all 4 years. Did well, but when I got to college I was shocked by the amount of work I was expected to do! Most schools have free programs to help - it sounds like you haven’t needed to develop these skills in your school, and it can be hard to figure out on your own. There are people who want to help - take advantage of the resources. As for whether your school will hurt you, some colleges do look at the “strength” of your high school, but not so much to penalize you as to see if you took advantage of whatever was available to you, even if the opportunities were limited. If they see you’ve only taken 2 AP courses, but that the school only offered 2 AP courses, then they know you took the most rigorous courseload that was available to you.</p>
