The issue is whether JoLaw824 has regressed. In general, if someone started with a higher score, and went down upon doing a statistically significant amount of questions, then the person is fcked. In this case, JoLaw824 was consistently hitting 70-74% of the questions correctly, but after having done roughly 2000 questions, the test-taker is hitting 58% correct. In conclusion, the examiners will likely find that JoLaw824 is fcked.
But seriously, if you've been looking over the reasoning for the answers you've gotten wrong, then you have this. Stone cold. I ran into a similar issue, although I wasn't fortunate enough to be hitting 70-74% before I "regressed." Think about it as if you're going to the gym... if you keep working the same muscles again and again, at some point your muscles will get fatigued and you'll soon be able to lift less and less until you give them a break. The rules and information is there, you haven't forgotten it. You just need to give them a rest.
I know you probably don't want to stop studying yet; I know I don't. So, mix things up a bit. What worked for me, although your mileage might vary, is study in a way that you haven't done so yet. Maybe go read some blog posts about a specific area of law, pick up a new MBE book you haven't read yet and read the discussions there, or do anything else you haven't already been doing so far. This will still provide you practice/studying you crave, but it introduces it in a fresh way.
