I never attended in an all girls school but I have been in an all girls class. Why don't you give it a try? You'll never know. Plus, the same thing Jolo said, it might help you focus on your studies and not just boys. But going to a co-ed school is fun. I just wonder, do these all girls/boys school have prom? Sorry, we don't have all girls/boys school here. XDD Well, if not, don't go to an all girls school. You'll miss the best part of highschool XDD
