Looking over the syllabus - The onus is completely on you to familiarize yourself with all the content covered in the PAT, which may be a little wider than your A-level syllabus.
PAT past papers - There are lots of past papers available online, and this is the best way to prepare. It’s important to do a good amount of practice, probably a minimum of four papers.
Extra problems - There are also PAT courses, where tutors will help you with mock paper questions, and help you hone and develop the necessary skills to succeed in the exam.
Practice More - Practice is the most important thing for the PAT, so make sure you do lots of times on paper! It is good to originally do some papers, not in timed conditions.
Working to Time Constraints - The PAT is time-pressured, so it is important to practice putting yourself under time constraints. Try and answer individual questions in short amounts of time.
Preparing your Mathematics - As lots of the test is focused upon mathematics, it is very important to practice your math's as well as your physics.
MAT Multiple Choice Questions - It is important to get fast when solving the PAT multiple choice questions. The best way to do this is to practice, and you can also practice the MAT multiple-choice questions to improve.
Long Answer Preparation - These questions are more developed than short answer questions. These are more likely to involve both physics and maths skills and require a little more time and thought than the short-answer questions.
