Just go to Practice --> Drills (on the top right). If your page shows as "Auto Builder" look at the bottom right corner and it will say "Advanced Builder". You can then select the questions you want to take as a section. For example, in the Logical Reasoning tab, look up the PT number you want to do and select the 25-26 questions you want to take as a section.

Hi! I would be interested as well. I live in PST and took the Nov LSAT.

I would actually recommend you to start out with the live classes! It's a more affordable option and you can attend different instructors' classes and see if you like their approach!
