How do I choose which short answer questions to answer in the exam (AQA)?

In a nutshell: choose the questions in which you feel you will get the most marks. The difficulty arises when the 40 mark essay question you want to answer is the same topic as one of the short answer questions you have chosen!To prevent this panic halfway through the exam, it is important to read through the entire question paper before answering any questions. I suggest at least five minutes to go through all the sections. This is one exam where I encourage the use of strategy! Looking at the 40 mark questions first, cross off those that you feel it would be impossible for you to answer for what ever reason (e.g. lack of knowledge). After this, highlight two that you would be happy to answer. Moving on to the short answer questions, in each section (human and physical geography) highlight the ones you feel you can answer confidently whilst also keeping in mind the 40 mark questions.If there are still clashes decide whether you think you can attain more marks by completing the 40 mark in that topic, or the short answers, and choose that one to do.
