IMHO, the fact that you are 50/50 on pass/fail (which I am too, and I’m not judging you on that) is a sign that you may not have been as prepared as you needed to be. how did you feel coming out of Level 1? I was like 90/10 pass/fail, and am also around 50/50 for Level 2. what i’m saying is, evaluate whether you can truly find new ways or strategies to get more out of your preparation - I know personally I did not feel as prepared going into Level 2, so I know there’s lots of room to improve. Band 10 vs Band 9 is a few questions, very marginal difference and may not be the best evaluator of whether you should retake or not.
