The specification provides an overview of the science and maths topics which BMAT Section 2 questions can draw on. Since time is limited, it is not efficient to work through the topics in the order they are presented. I would recommend first doing a comfortability test by skimming through the document and ticking the topics that you are confident in solving problems. Then, begin working on the unticked areas before moving onto ticked topics. You can find a more detailed step-by-step breakdown here.
The official papers are more than enough to practice questions. However, if you are looking for step-by-step guidance in tackling the different question-types, then a course is a good option. Medify is great because it is affordable. Pros – the course provides tutorials to teach exam content and includes practice questions to put strategies to the test. The course also includes detailed essay plans for all section 3 past papers and an excellent user interface to go through official papers. Cons – tutorials are mostly text, no timing feature included when attempting past papers. Click here to visit Medify.
Getting a question wrong during BMAT practice offers the opportunity to learn something new about the exam and yourself. But improvement only happens if you are reviewing questions the right way. I recommend analysing questions at three levels. 1 – the Stimulus type (the material being analysed), 2 – the Question type (the kind of question presented) and, 3 – the Skill/Reasoning type (the skill/reasoning required to solve the problem). Most students only analyse the question type, and sadly this doesn’t paint the full picture. You can find a more detailed explanation here.
