During the Exam

• Allocate Time Wisely: Before you start each section, take a moment to allocate your time wisely. For the multiple-choice section, aim to spend about 1.5 minutes per question. For the free-response section, allocate about 15 minutes for each long question and 7-8 minutes for each short question. Keep in mind that these are just guidelines, and you may need to adjust your timing based on the difficulty of the questions.
• Pace Yourself: Don't rush through the exam. Take your time to read each question carefully and make sure you understand what is being asked. If you get stuck on a question, don't spend too much time on it. Move on to the next question and come back to the difficult one later if you have time.
• Answer Easier Questions First: Start with the questions that you find easiest to answer. This will help you build confidence and momentum. Answering the easier questions first also ensures that you secure those points before moving on to the more challenging questions.
• Skip and Return: If you encounter a question that you're unsure about, skip it and come back to it later. This is especially important on the multiple-choice section, where you can eliminate obviously wrong answers and make an educated guess.
• Use All Available Time: Don't leave the exam early. Use the remaining time to review your answers, check your calculations, and make sure you haven't missed any questions. Even if you're confident in your answers, it's always a good idea to double-check your work.
