Well, after all, you chose the RE (GCSE) courseworks, so there is nothing to regret about. Instead, concentrate all your attention on getting ready for writing an RE coursework. The better you study the fewer problems you have.
 
An RE coursework presupposes some knowledge of philosophy and ethics. If your knowledge is below the medium level, there is not much you can hope for. The point is that theoretical framework for RE coursework is extremely big and impressive. Starting from antique times philosophers have been working on at least dozen different philosophical problems. You have to be aware of at least half of them. Therefore, an RE coursework should look like this:

1. An RE coursework is an organized piece of writing where all of the chapters have to follow a certain pattern of organization.
2. No one yet cancelled such important parts of an RE coursework as thesis statement and supporting data. Work on a thesis statement thoroughly for it is going to be the main part of your writing. Do not fall into common mistake when choosing supportive data for an RE coursework thesis statement. Stick to the data that is reliable and unbeatable.
3. An RE coursework can also include Methodology part that seems pretty interesting regarding the topic of your work. As a researcher you can include two quite interesting and depictive methods. One is the field trip, that is certainly time-taking, but if you know what to look for, the results will be a reward good enough. Another method that is useful in RE courseworks is the survey. The information you receive may be as helpful, as the theory itself.
