Which ap exams are the best/easiest ap's to study for?

I would strongly advise you not to self study for AP environmental science. Although the class is considered one of the easiest APs, the exam has the second highest fail rate (next to world history). None of the tests are "easy" to study for, but I would have to say that the English tests would be the easiest. Not that the tests are easy, just you can't really study for them anyways, so all you would have to do is take some practice multiple choice tests and write some essays. Human geography is a good choice, as it's supposedly really easy. Government would have a lot to learn, but it would be extremely straightforward, so that's a good choice. Oh! I just noticed your last comment haha. So if you are confident that you did well on the world history test, you should do fine in everything else because it's the most failed!! And another suggestion would be the AP biology test because I just took that and it was really easy....

take only the things you are genuinely interested in, or you will fail.
