What studying method do you recommend I use if I have to study for a test? (Ex. Flash cards, practice questions, etc.)

Practice questions, organized together, can provide productive study. If you create your own practice questions, perhaps from your detailed notes, creating/organizing the questions can itself be a powerful exercise in learning the material. Then, you must be disciplined in answering the questions without referring to your notes, then later reviewing the accuracy and completeness of your answers, and using the results to target areas for deeper study.
