I know many people say the key to improving their mock scores and passing the exam is to grade their own mocks as objectively as possible. Would it be a better idea to trade mocks with another Level 3 candidate that you trust?
on reddit we had (still have) a tight group of homies in a group chat- we would all do the same years’ paper (say, 2011 for example) the same morning or whatever and trade them with each other for grading and post-write discussion. I suggest you do the same; network on social media and form a group with like-minded people
+1. Grading mocks is also good prep for the exam. It forces you to think about the questions from a new angle.
