…my last mock a few days before Dec Level 1 in 2017 was 52%, and I didn’t once break 60% before that. I ended up passing comfortably. I just about passed Level 2 first time this year, and my highest mock was 58%, and that was an outlier.
On both occasions I’d already pretty much written it off in my head as a waste of time, and that I was just going for the experience.
Moral of the story, keep going. Take the afternoon/evening off before, and relax. You know more than you realize, and it’s not over until it’s over.
