AQA Physics Paper 2 Higher Combined Science Predicted Paper 2022 Name ……………………………………………… Date ……………………………………………… 1 hour 15 minutes allowed Similar to your real exam, each question in this paper gets harder towards the end of each question, so if you find you can’t do the last part of a certain question, try the next question – they all start off easier and then get harder. Grade boundaries These are VERY rough guesses! Getting an 8 or 9 on this paper does not guarantee you the same mark in the exam. • 9 55 • 8 45 • 7 35 • 6 25 • 5 15 The information from the exam board gives us a broad overview of what is covered in the exam. If a topic is not listed as a ‘major focus’ it can still come up in a question, but that question might not be worth many marks. There are questions in this paper that cover topics that are not a ‘major focus’ for the exam, but don’t let that worry you!
