Okay, so everyone keeps telling my to stop wasting full PT's and just start drilling.
What do you all mean by drilling?
Should I buy all these http://www.cambridgelsat.com/problem-se ... reasoning/
and start going through the questions?
Is this what you all mean by drilling?
If I do buy these packets won't this give me too much familiarity with the questions and then give me a false idea of when I take actual preptests?
Most people use the earlier PTs (1-39) for drilling just for that very reason. The earlier PTs aren't as relevant as the newer ones for a couple of reasons, but they're still very valuable practice.
And the entire point is to build up familiarity. If you truly understand how to do linear games, then no fucking linear game that LSAC can ever come up with, provided that it matches the concept that they used previously, will be difficult. If you truly understand how to deal with sufficient assumption questions, then all sufficient assumption questions are solvable. This is why the whole "Oh shit! I'm out of new material!" is not as big an issue as people think it is.
As for outright memorizing things- I've taken just about every existing LG 3 or 4 times now. The ones that confounded me, a lot more. It's only the ones that I've literally dissected and spent hours on trying to understand that I remember, and even then I only remember the details as in "Oh, this is the stone and mulch game!, or "Oh, this is the bus game!" Yes, I will remember key inferences of games that I've reviewed to death, but that's sort of why you make it a point to understand how you came to that inference moreso than the actual fact that you made the inference.
Put it another way - You spend time trying to memorize math equations and principles and whatnot by drilling them to death because you expect them to pop up in the test. Memorizing the common inferences and processes that LSAC use is the same thing.
