Hi Hodgicus,
I did an EPQ with AQA (AQA seems to be the most popular EPQ exam board, so here's some advice for AQA as I don't know much about the other boards)
With AQA there are basically 2 formats you can choose from:
1) A 5000 word essay + presentation + Log Book
2) An artefact + 1000 word essay + presentation + Log Book
Assuming you chose to do the 5000 word essay, a format like this would be good:
1. Introduction (bear in mind that the introduction is often easier to write at the end of the project)
Start by introducing your question, for example: "The question I am researching is '[question here]'", then explain the aim of your project, i.e. what you plan to find out. Also mention what sources of information you will use, and how your essay is going to be structured.
2. Main essayHere you should discuss all of the main points and arguments which will help to answer your question. This should be the bulk of your essay; remember to use paragraphs and reference any quotes and images you use so that the examiner can refer to them in the bibliography.
3. ConclusionIn the conclusion you should briefly discuss the most significant points/arguments again and come to a conclusion which answers your original title question.
4. BibliographyThe bibliography should include sources for all images and quotes you use in your essay. Keep a note of the date when you found each source as well and add them in square brackets after each source. If I remember correctly, you need at least three different types of sources of information, for example a book, a website and a TV programme – you get marks specifically for doing this. Also remember that the bibliography should be kept separate from the main essay; I'd suggest keeping them as two different documents.
The presentationWhen you have completed your essay, you’ll need to give a short 10-15 minute presentation on your EPQ topic. The presentation should have slides dedicated to the following: why you chose to do an EPQ, why you chose your specific title, sources of information you used, what you found out, your conclusion, any problems you encountered during the project, benefits of doing an EPQ, what you would do differently if you did the project again, and whether you would recommend doing an EPQ to others. There must also be opportunity for the audience to ask questions, either during the presentation or at the end - this is to fulfill the criteria of having an 'interactive element'.
The Log BookThe last component of the EPQ is the Log Book (I think it’s also sometimes called a Production Log) - remember to fill it in thoroughly because this is the part which gets you most of the marks. You fill in the Log Book at various stages during your EPQ: at the start, middle and end of the project.
Inside the Log Book there is guidance on what to include, but I found it very vague, so basically at each stage you’ll write about 1) what has gone well and what has gone badly, 2) any changes you have made to the project e.g. the title, structure etc, 3) what you plan to do next, and 4) any recommendations from your EPQ mentor/supervisor. You also need to write about your presentation, but again, the Log Book will have instructions on what you need to include.
I hope this gives you a better idea of what to do; if you have any more questions feel free to message me (I got an A in my EPQ)
