Hello, I'll be starting grad school soon after taking two years off since undergrad. As a review, I'd like to go through all of Halliday Resnick and Krane's 5e "physics," doing as many problems, questions, exercises, and multiple choices as I can. Does anyone know where I could find an answer key for the multiple choice and questions (I have the instructors solutions manual but it only has exercises and problems)? Since most of them are so elementary it doesn't make much sense for me to verify each one individually; I'd like to just go through the entire book in a few days and check my answers quickly to make sure my time off didn't warp my understanding of basic physics. Thanks in advance for any help you might be able to provide.
