Revision is a very personal thing, and it is difficult to provide useful generic advice about how to revise. Different types of exams also call for different revision techniques too. However, I often suggest to students that it may help to devise a template that you can use for each topic that you have studied, whether for closed book or open book exams that rely on essay or problem question formats. Revision is not really about memorising lots of facts, even if the exam is closed book. Instead, it is about making sure that you understand how the general principles fit together so that you can see the big picture (the whole topic) as well as the detail underneath. It is also important that you can make use of your knowledge too, and apply it to the question and draw conclusions that are relevant to the matters that you need to discuss. Revision should also include the evidence that you need to demonstrate the principles that you will use in the exam to answer the questions. Of course you do need to be able to remember the big picture, the general principles and the evidence, but for most exams you will need to use this knowledge rather than just write down what you can remember.
Some of you will have already devised your own tailor-made approach to revision. However, some of you will have relied on a very good memory so far, and may find this method is not as effective as it once was in the face of increasingly complex concepts and the volume of material covered in your law modules or courses. I have included the revision template that I encourage my Public law LLB students to use, until such time as they have their own with which they feel confident. You may wish to use this as a starting point, and then amend it to suit your needs.
