Are you basically saying you have a copy of one of our workbooks, but you haven't been exposed to any of our strategy guides / class content?
If you're essentially asking, "How do I study Reading Comp for LSAT", that question is a little too broad for the purposes of this forum. But if you scan through previous posts about RC or try a few passages in your book and then read through the explanation threads we have for those passages on this forum (by going to RC --> that test ---> that passage --> that question), I think you'll absorb a lot of our teaching points and strategies.
Here's the link for the central RC hub:
