I was just wondering if it’s possible for me to apply for early admission to a college while I still have to take my required biological science class in senior year?
I’m not 100% sure but I think they would see that you’re scheduled to take that class. I don’t think it would be an issue
You can apply Early Action, Early Decision or Single Choice Early Action to any schools that offer one of these options, if that is what you are asking. They will get a copy of your transcript with your classes for senior year listed even though there are no grades available.
Is this question coming up because you want to major in biology? Schools consider your indication of interest in a major to be just an indication. It’s non-binding. Many students change their major at least once and the schools know that. Undecided is equally acceptable as an answer to that question.
