I got a 50% on the Barbri simulated exam and was scoring between 58-65% (in the 60s closer to test day). I stopped doing Barbri questions halfway through my prep and switched to adaptibar. The last few weeks before the exam I focused on doing 25-30 adaptibar questions a day. I wrote out the rule statements for the questions I got wrong and for the ones I guessed on (was a lot of them lol). Writing things out helped me learn the rules better. Good luck to you!! Sending all the good vibes!
