“Revision is considered as ‘revision’ by teachers and lecturers, when a lot of the time it is ‘learning for the first time and desperately trying to remember’ for students.” – Rebecca Pickavance [Source]
This is a great insight into what many students don’t understand about revision.
Revision isn’t cramming. Revision isn’t learning new stuff a night or two before a test. Revision isn’t picking up a few essentials so you can pass.
The main purpose of swotting up before exams is to remind yourself of what has gone before. You should already be familiar with the content. As you learn over time, links are made and learning takes place gradually. But some of your knowledge fades away as you spend time on other things.
To get back to optimum understanding, you revise.
Revision is refreshment. You go over the learning you’ve already done and bring it back to the front of your thinking. You may not have mastered the subject back to front, but you have enough understanding to have clarity and confidence when you need to use what you have learned.
Think of it as switching on a set of lights. You don’t install the wiring and fit the bulbs every time. You’ve done the hard work once and you’re left with the simple task of switching the lights back on. You still have to get out of your seat and press the button, but that’s all. And with enough connections, you’ll only need one switch to turn all the lights on at once.
When you revise, how much is new to you? How much are you properly learning for the first time here? The less it is, the better.
