I feel overwhelmed by the number of LSAT prep options. I do well on the LSAT practice exams, I regularly get a 170, but I want to push my score up to 179 (give or take a point). What tools will really push me to the next level? I prefer prep books, but I also can do online, or a tutor if need be. Help me Obi-Wan Kenobi, you're my only hope.

Are your 170s strictly time under testing conditions (i.e., no breaks)?

This is too vague.

Where are you missing questions?
Are you timing yourself strictly?
Are you using digital or regular prep?
How long do you have to study?
How many practice tests have you taken?
