I'm not very familiar with how college admissions work. One question I have is if people send their applications in Junior year, and why? My school doesn't offer AP Chemistry or AP Physics but does offer PSEO classes. PSEO classes are dual enrollment classes; they're pretty much just college classes. However, the prerequisite to PSEO Chemistry and PSEO Physics are taking Chemistry and Physics in high school. I think I can take Chemistry in tenth grade, but I'm pretty sure I have to take Physics only in 11th. However, if I take normal physics in 11, I can't say that I took the PSEO course if I send in applications in Junior year. Is there a reason you should send in applications in Junior year? The reason I ask is that I've heard many people say they did that or will do that, or that others should do that.
