University applications?

Yes you will start applying for colleges in the fall of your senior year. Most schools have deadlines in early January or February while other have deadlines that are later around May. Do not make your course load easier. Colleges will see this. When you apply to colleges they will also ask for your senior year cl schedule to see what you are taking. If you are then admitted into a college they will ask for your final transcript to see how you did in those courses. I have heard of some schools that will accept a student but then reject them when they submit their final transcript and see that the student slacked off their senior year.
