Hi Courtney,
Apologies for our slow reply. A few questions on the forums slipped by us recently.
The general answer to "how long should I study" depends very heavily on what you are currently scoring on the test, and the amount that you need to increase your score in order to reach your goal. That's one reason why we assign a full practice test in the "Before Session 1" assignments. If you've already taken practice test or an actual LSAT before starting Interact, you can use that as your guide. Someone who wants to increase their score by five points or less might only need a bit of help. Someone who wants to increase their score by more than 10 points will probably need to work through the Interact lessons more intensely and do more practice on their own afterward. It helps to keep this in mind as you look at the answers below.
1) How far in advance of the LSAT should I finish the LSAT Interact course?
It's a good idea to finish at least two or three weeks before your test day. As you noted, it's not ideal to learn a lot of new strategies right before your test date. During the last two or three weeks before the test, you'll want to focus on reviewing, reinforcing, and cementing your existing processes and strategies instead of trying to learn a lot of new content.
2) What should I be doing in addition to the course?
The course itself contains a lot to keep you busy, so I'd just focus on that. If you have extra time and want to do additional work, spend time reviewing content that you find difficult. It can be helpful to redo Interact lessons and reread chapters in the Strategy Guides. Beyond that, spend time reviewing questions that you found difficult. Replay games that you found difficult. Reread RC passages that you found difficult. This kind of review is extremely valuable and often underrated.
3) How much should I study per week up until the September LSAT?
The best strategy is to spend as much time as possible right now. If you spend as much time as possible now and feel like you're making more than enough progress, you can easily taper off later.
If you have nothing else to do but study for the LSAT and want to spend six hours a day doing that, great! On the other hand, if you have a full time job and a limited amount of time for LSAT prep, fit in as much as you can on days when you're working, even if it's only 30 minutes or an hour.
Always, always reserve at least one day each week where you do no LSAT prep at all.
Do not study for the LSAT every day. If you want to take two days off per week, do that.
4) How long should it take me to complete each section of the LSAT Interact?
That varies greatly from person to person. But this connects to question #2 above. If you're wondering whether or not you should be doing the Helpful Additions, go ahead and do those before you worry about doing extra work outside of the Interact assignments.
Many people are seeing a lot of new and unfamiliar information when they first start preparing for the LSAT, and the going can definitely feel slow in the beginning. Keep at it, and you might find that things move more smoothly and a bit more quickly as you progress through the course.
5) Should I focus more on weak sections?
I wouldn't cut back on stronger sections to focus on weaker ones, especially since you mentioned that you're near the beginning of the course. The initial lessons cover a lot of foundational concepts that we build on in later sections. However, if you have extra time to review and want to devote that time to weaker sections, that's a good idea.
Hope this helps!
