honestly, I don;t know if TIME is all you need to do good on the test. You really need to understand why your answer is correct and if you got it wrong, then why it is wrong and why the correct answer is in fact correct.
The LSAT and the type of logic in it, at least for me, was a new way of thinking and it took some serious understanding and TIME( I concede this pt.) to panic on my December test (which I canceled), get a 160 in Feb, and now have to retake in June.
Another thing that helps with the LSAT is lots of confidence, which is what I really lacked my first time, and improved on my second time. Confidence Confidence Confidence, just not OVER-confidence
