Hi Anne,
Thanks for the question! That inconsistency you are seeing relates to how the LSAT tests a wide variety of areas each time, which makes some tests better for you and some worse. I talk about that here:
http://blog.powerscore.com/lsat/bid/310 ... sat-casino. For students who aren't 100% on the fundamentals or who aren't machine-like in their approach, these variations in exams often reveal themselves in varying performances. LR is great on one test, but then not so great on the next while LG seems to do the same thing, but on different tests. You fix it by doing the following:
- 1. Tracking everything that gives you problems. Miss a question? Mark it down and why. Don't feel 100% comfortable? Same thing—mark it down. Then, every so often, go through those lists and look for patterns in what you are missing. There will be patterns!
2. Make sure you really know the concepts and techniques. For example, can identify premises and conclusions without thinking, do you know the basic argument flaws, or do you know all the ways to break down causality in LR, and so on. Instant execution with no delays is your goal.
3. You look at questions repeatedly until they are second nature. Review, review, review. Stumble on a question? Look at it again a few days later. Get to know questions so well you could teach it to your friends without missing a beat, and without stumbling over any of the ideas.
Perhaps most important, inconsistency often relates to your analysis of the stimulus. How good do you feel coming out of each stimulus? Do you feel like you understand what is being said? Is your clarity on the argument as good as you'd like, or do you find yourself uncertain of exactly what has been said in many cases? If it's the latter, then the first place to start is with that—in those sections of untimed questions, stop after the stimulus and make an assessment of how strongly you feel about your stimulus understanding, and then compare that to how you perform when answering each question. If you see a connection between problems with the stimulus and missing questions, then you'll know that has to be part of your study focus.
In other words, each step of the way through a problem is an opportunity to get better and to really make sure you have everything in place. The good news is that since you can do well on individuals section, you've shown you have the ability. Now you need to eliminate those weaker spots, which will help create a more comprehensive and consistent performance.
Those are broad sketches, but hopefully that helps. Thanks!
