Look for Common Concepts Across the Past Papers
Go through the last few years (we usually do 3 years) and write down each main concept that pops up. If you’re confused about the ‘main concepts’ for your specific exam paper, have a look at our StudyTime Checklists, which summarise each exam, and break it down into the main concepts that you’ll need to know.
Once you make a list of main concepts in each exam paper for the past 3 years, you’ll notice that the same concepts are repeated each year. The most common concepts are the ones that you should focus on. It’s not guaranteed that you’ll be asked those questions in your exam, but they’re your safest bet, and those are the most important things to focus on when you’re cramming for your exams.
