Hey everyone,
I'm sure there are several past posts like this, but -- for anyone taking the upcoming December test -- I think it's important to clarify: quality over quantity.
I originally planned on taking a preptest a day to get through some stray 60s tests I didn't do + the entire 70s series + available 80s before the LSAT. After an unexpected day off a couple days ago, I went -1 on the whole LR section. I had never done that before. I was probably averaging around -4 to -6 combined. Out of curiosity, I decided to only drill LG the next day and BR a little on RC and LR, without doing any new questions. Took another preptest after that break and went -2 combined. A third preptest produced the same result, all but confirming what JY already tells us (but what many of us are probably reluctant to accept): do not PT more than 3 times a week.
I've let go of the idea of doing the whole 70s series before the December test (other than LG), and I've accepted that the brain is not a computer; we don't choose when and how often it can be charged to satisfaction. For me, doing a preptest every other day has produced a consistent jump in scores that I hardly attribute to "knowing more." So, if you're cramming for the test, consider taking a break from this stuff. I know for one that I'm not touching anything LSAT related the day before.
Best of luck on the final stretch
