The most stressful parts of the IB exams (especially HL) are Papers 2 and (if HL) 3. Seeing as how you will only have about 30-40 minutes to write each essay, your 5 minutes of preparation time at the beginning of each exam should relate mostly to content, not format. A grade 7 essay is structured, concise, relevant, and nuanced. If you hit each of these points, you are guaranteed to write an excellent essay.What makes an essay structured? The PEEL method, which stands for:Point - a topic sentence to open up your paragraph,Evidence - a relevant fact that supports your point,an Explanation of your point's relevance and importance in the grander scheme of things (this depends on the question), anda Link to your thesis statement and your next body paragraph (or conclusion).Each paragraph should have a specific purpose to it, given in your topic sentence, which will either further or oppose your argument - meaning every fact or piece of historiography you include should be both concise and relevant. The complete structure of your essay depends on the question given (be it a 'To What Extent' or 'In What Ways' question), though you should at all times nuance your take on that question by keeping into account not only what different historians thought, bu also what you think. This will lend itself to a more personalised and standout essay.
