As for your scores, I'll accept that you have "no major issues" with question types, that you "understand everything," and that your pacing is improving. If that is all true, then your plateau is due to test anxiety. Test anxiety comes from two places. First, from an irrational fear of failure. This happens when we, in our minds, exaggerate the importance of the test and the negative effects of not doing we well as we would like.
I am sorry to have to disagree with this one aspect. Everything else is right on point, but there are more issues than just text anxiety that result in people not achieving 160's. It is certainly an important factor, but again the vast majority of test takers do not get a 160 or above. Most people don't get straight A's in every subject they have strengths, weaknesses, andlimits. To imply the only reason for a lower score is text anxiety is a bit conclusory. I may have it mistaken, but I thought I read somewhere you had a 170+ LSAT, which is f*ng amazing! However, the vast majority of people no matter how much studying they do are unlikely to achieve that or even if they have no anxiety whatsoever.
@Earl, first....LOLOL at the "cue Julie Fern" comment!!! Thanks for your ideas! Perhaps some of it may be anxiety. Perhaps I am exaggerating the importance of my score and all the negative effects of a bad score. Your point about comfort and familiarity really made me think, though. LSAT questions are definitely not as comfortable as simply math problems under a time constraint. But how long does it take one to get that comfortable with LSAT questions? It seems like most LSAT takers only need a couple months of prep to improve their score. But my score has never improved, not even one point, since I started studying months ago. Will it take 2 years of studying for me to get comfortable enough with LSAT questions in the time constraints? Does it take some people a much longer time to start to see improvements? Or is it possible that I will never, ever be able to do any better than my diagnostic of 149? I'm so hopeless right now that I think I'd even be happy with a practice test just one or two points higher than my 149 diagnostic/best/current score. But right now, even that seems unlikely. Is there anything I can do? Or is my case hopeless?
