Pretty easy, overall.
I wouldn't recommend this course because this course is not intensive preparation. Intensive preparation means the teacher gives out a lot of homework exercises and tests to successfully prepare the student to take the AP exam.
Even though my teacher did not teach much, I taught myself the Law of motion(velocity=distance/time) and many applications of Newton's Law(gravity and vectors and friction).

Advice for students:
Make sure you read the textbook, because most AP teachers like the texting more than talking to real people(students).
