Information from the College Board for current AP students
Here's some more information from the College Board regarding the May AP exams. It's good information to have but students need to remember that the situation is fluid and can change overnight.
For now, take a look at your AP class and what's going to be covered in your exam. Try to keep up with your classes and if your teachers haven't gotten back to you about their lesson plans, give them some time but start working on assignments that you already have.
