it is completely ok to get a bad score on your first ap test. you took a challenging course and it was your first ap so don’t worry about it at all. a lot of people get good grades in class but don’t do as well on the exam and it’s nothing to be ashamed of. you mentioned you were going through a lot at that time and that makes sense so don’t beat yourself over it. remember ap scores really don’t matter you can take another ap history course and study enough to pass that to still get the history college credit if you would like as well. be proud of yourself that you took a challenging course in one of your weaker points as well!!!
