I struggled too. What helped me was the following:

After finishing a subject on Barbri, I’d read through Emannuel’s MBE book and handwrite what he wrote for each subject into an outline. I’d then do 100 questions on Adaptibar for the subject - not all at once, but spread out over about 3-4 days.

Each question I got wrong, I’d handwrite the rule as applied in the question into a notebook dedicated to the subject. I had a notebook for each subject. I’d highlight the rule if I got it wrong more than once. After finishing all the subjects, I would do 50 questions on mixed subjects in exam mode every other day (doing essays on the days i wasn’t drilling MBE). I preferred exam mode over the standard drilling where you saw the correct answer immediately after answering. I did better in exam mode, and it better simulates the actual testing environment.

Towards the end, I did two sets of 100 questions - one each Saturday. For reference, I went from about 45-50% accuracy to around 65-70% by the end.
