Would these prep books be a good way to practice for the multiple choice sections of the exams (both English lang and lit)?
Yes! I used Cliffnotes for AP Lang last year and it was really helpful! I actually found the review questions to be more difficult than the ones on the actual exam, so I felt really well-prepared. I’m not sure about Lit, but I would think that if it was good for Lang then it would be good for Lit too. Good luck.
