How to get an A in Science GCSE Watch
I seriously advise looking at past papers, answering the questions and then looking at the marks schemes. You need to identify which marks you are missing out on. If you are missing marks through lack of understanding then you will have a lot of work ahead trying to learn the science. However, you may find you are only missing some exam skills (like the linking example above) if this is the case you should be able to train your grade up with relative ease.
