Do colleges measure the number of APs as the number of exams you take or the number of AP classes on your transcript?

I would say that they kind of look at both. This is because having AP classes on your transcript means that you are at least taking the risk of attempting college-level classes; getting good grades on them means that you can handle the coursework. But arguably more important is getting a good score on the AP exam because it shows that in addition to handling the coursework, you also truly understood the things that you are learning. As for your specific case, I'm not even sure how your classes work because unless your school somehow crams an entire AP course within one high school semester, I don't see how the entirety of the course is being taught. However, I still think that those classes, despite being during the same period and also with the same teacher, are different classes by definition according to College Board. I understand that the system at your school is unique, but I don't think that takes away from the fact that they are different classes unless the classes are not being taught in full. Just make sure that you are taking the AP exams for both because it's kind of a waste of a class if you don't plan on taking the AP exam.

So I’m not sure if it direct answers your question but I take AP Macroeconomics and AP Microeconomics. These are 2 seperate classes as there’s a distinct test for both of them. But AP IS History is 1 class.

You evaluated by the classes (each class ahas a test that goes with it) not by tests.

Hope this helps and feel free to comment if you’s like clarification as I’d be more than happy to help!
