How to get started?

Hi folks,

Im new to this whole lsat business. In fact, I've been putting off starting studying because...we'll, frankly, I'm not entirely sure what to do? I took a diagnostic and got a 163 but im not sure where to go from there. Do I just start drilling? I understand the basic logic behind the questions just fine, I think. Its just a good number tripped me up, so I dont think I need introduction to the base concepts.
