As others have said, there’s really no downside to taking it, unless money is an issue. Last year with covid, the AP Exams went online and the APUSH material for the AP Exam was reduced. The Exam also significantly shortened. My son who took it, said it was a total joke. It normally is not a total joke. I also wasn’t overly impressed with his teacher compared to the teacher my other children had so either the test was a total joke, or the teacher did prepare them better than I thought. It’s hard to say.
That said, this year like you are saying, AP as of now is not planning to shorten exams and is planning on having them be in person. I am concerned for my son this year who has not even been in school since last March. I don’t know how he can be prepared when he sees his teachers remotely for way less time than if he were in person and don’t feel how he can adequately be prepared and probably less so than any student who has been receiving in person. The teachers are great, it’s just not enough time to get all the material in. This sounds similar to your experience. Many students have had full year in person or hybrid. They will have significant advantages to those who have been fully remote.
But that said, there is still no downside to taking it. If you do poorly, you just don’t get the credit in college If you do well, you also may still not get it. Or, you might. My other kids, one school doesn’t even take APUSH credit no matter what score you get. The other one got the credit. So ultimately if you don’t even know where you’re going to college, you can’t say if it’s worth it or not to take. It’s similar with AP STats. A lot of schools don’t take it at all. My daughter knew her college didn’t take it but still took the Exam because if she ever decided to transfer she had that score in the bank. She hasn’t transferred, but our downside was only the $94.
It’s ultimately a personal decision. There are also some great AP resources to use to prepare for the APUSH Exam that may be better than what you’re getting at school. I would go check them out. I can’t remember if it was the AP Barron’s book that is the good APUSH one or not, but if you research online, you’ll find which one is most recommended.
