I'm an upper-division physics student. I have finals coming up next week and I want to take the advice of one of my professors from several years ago: write your own exams for practice and give them to peers. It'll help the test writer to review topics and your peers to have practice questions. However, my finals are all upper-division physics exams. Quantum mechanics, electricity and magnetism, and statistical thermodynamics. Homework and exams are generally pretty difficult, and I'm not sure how I can write an exam that will be on the same level that we can expect on the final.
Does anyone have any suggestions on how to make up questions to create a practice exam for study purposes?
