Use flashcards to test your knowledge of key terms and concepts. Quiz yourself on the material to identify areas where you need more practice.

Space out your review sessions. Instead of cramming for hours the night before a test, review the material in shorter intervals over a longer period of time. This technique, known as spaced repetition, has been shown to be more effective for long-term retention. Use your highlighted notes and summaries to quickly refresh your memory before each review session.

4. Practice Questions and Past Papers

To really nail the material, you need to practice applying your knowledge. Work through practice questions and past papers to get a feel for the types of questions you'll be asked on the exam. Identify the topics that you struggle with and focus your review efforts on those areas.

When you're working through practice questions, don't just look for the right answer. Try to understand why the other answer choices are incorrect. This will help you develop a deeper understanding of the material and avoid making similar mistakes on the exam. Review the solutions to the practice questions and make notes on any concepts that you need to revisit.

5. Seek Clarification and Collaborate
