Synoptic Essay, Biology AQA

Best way to revise is knowing the content really. If you'd like to practice, then come up with some essay titles (try to make it challenging, for example, try writing an essay on genetic engineering or something). The most important thing about your essay is your plan- if you write a really good and detailed plan, you really will have no issues in writing the thing. Perhaps take a look at some essay titles from the past and spend 5 or so minutes in writing out a detailed plan, showing how you can also link certain parts of it. In general, you should be aiming for a minimum of 5 areas of biology in your essay. So yeah, I think that rather than writing out whole essays for practice, focusing on getting a really detailed plan is more important, like I say, as long as your plan in the form of a spider diagram is good, you'll get far with your essay as long as you know the content.
