Advantage #1 - They are the real deal
Past papers are not just mocks made up by your teacher or head of the year. These are actual papers that real students like you have attempted in the past few years. The most practical assessment form is as realistic as possible, as close in content and feel to the real test as you can muster. Nothing can surpass past papers in this regard.
Advantage #2 - Realistic training of time management
As you practice past papers, you can become increasingly familiar with the time requirements for each question and learn to control your time and maximise your efficiency. It is one thing to have all the knowledge inside your head, but GCSE and A-Level exams follow patterns where some sections are worth more points than others. When you are familiar with the papers, you can practice finishing low-mark questions quickly to spend more time on getting the big-mark questions done well. The odd mark here and there you can afford to lose, but not one of the critical questions. That is where final grades start to slip.
Advantage #3 - They clarify your strengths and weaknesses
Answering fundamental questions on past papers will show you very clearly where your strengths and weaknesses are currently. You can quickly answer the questions in the first part of the paper, but you constantly struggle with the same kinds of questions. You will also reveal the gaps in your knowledge. If you are asked, for example, to answer on reasons behind Louis XIV of France’s religious policy and its success or failure, then you know to go back and study that part in detail. Never forget that while the content may not appear in the same section in the same format, it might appear in another, so fill in those gaps as best you can, as indicated by your past paper practice.
Advantage #4 - They cover much ground
When you finish just a handful of past papers, you might cover half or even more of the topic areas that you are supposed to cover in this subject. It is an efficient way to sweep across different topics broadly, which links up handily with Advantage #3. The more topic areas you can cover, the more likely you are to discover the fatal flaws in your knowledge base.
Advantage #5 - You will be able to distinguish the different “command” words
All questions on all papers across all subjects will feature one or more “command” words that indicate how exactly you should approach your answer. You must have a strong understanding of the differences between, for example, “explain,” “outline,” and “analyse.”
