Best LSAT Prep Class?

<p>I'm starting to look at LSAT prep classes to take this summer and I have no idea which one to take.</p>

<p>Kaplan, Princeton Review, and TestMasters are the big three, I just don't know which to pick.</p>

<p>Any insight?</p>

<p>Powerscore</p>

<p>Testmasters, Powerscore, Blueprint are the good ones</p>

<p>Kaplan and Princeton are terrible. I've heard people getting lower than their diags after them.</p>

<p>I’m currently a junior transfer student. So, my question is: What is the earliest to start studying for the LSAT?</p>
