First and foremost, if you're not ready yet, then I strongly suggest that you consider pushing taking the test until December. Getting ready for a tough exam like the LSAT in just ONE-MONTH can cause 1) physical damage (i.e., I've seen students lose hair) and 2) even worse, psychological burn-out (i.e., I've witnessed students end up hating the very idea of law school). So strongly consider postponing taking this test.
However, if you are resolved to take the test within the next month - pay attention. Students who DO NOT go through 10-15 practice exams rarely do well on the real LSAT. This last month should be spent taking real LSAT exams under strict timed conditions AND more importantly reviewing your mistakes thoroughly and learning from them.
1. Collect PT 55 (Oct 2008) to PT 69 (Jun 2013)
Do it quick. If you're self prepping without a prep company, then quickly go on Amazon or LSAC to purchase your single-booklet copies. These exams have been known to run-out. Pre-prep and organize these exams in easy to access booklet/packet form.
2. Be Disciplined: Set a Schedule and STICK to it!
Discipline. This is so important. It is the key to anyone's success on the LSAT. It's so easy to get gung-ho about something on the ouset. But it's just as easy to lose flare and interest. Commit to, for example, waking up at 7AM on Saturday mornings and taking a full-length practice test.
Here is a schedule I have most of my class and tutoring students follow:
Light Red = timed mock exam
Light Blue = untimed mock exam (but do it in one-sitting)
Light Orange = review and practice drills
Light Green = rest rest rest
If you have one-month of prep left, I advise you to try the above schedule as well. The above schedule essentially goes through 15 practice exams in one month. It does so while providing two days of rest per week. It's very practical, manageable, and effective. However, without discipline, no amount of scheduling and planning will help you.
3. Meta-Cognition: Review, Think, and Find-a-Pattern
When you get an answer wrong, it's important to do a good job of reviewing your mistakes. Often students merely look over the accredited response, nod, and move on. It's NOT enough to merely understand why the correct answer is correct. That's like being spoon-fed. Who knows if you would have ever been able to arrive at that answer on your own, if someone else had to point out what was correct to you? Also what about hind-sight bias? When you already know something is correct, then OF COURSE you "get it".
As you score your completed exams, simply put a X on the question number(s) you got wrong; DO NOT mark/circle the correct answer. You want to be able to redo the questions you got wrong without knowing the correct answer. So do that. It's doesn't matter that you already know that one of the answer choices is incorrect - you still got it wrong and you can learn a great deal from redoing the question.
Think about why you chose the wrong answer. Think about what you missed while reading the Vignette/Stimulus. Think about what the question stem is prompting you to do. Think about how this question is like/different from all other similar question types. Think about your pace. Think about what you were thinking the first time through. Think about why the wrong answer are wrong, and the Dudds are dudds. In short, be able to teach this entire question to someone without any hiccups.
Finally, figure out whether there's a pattern to your mistakes. Patterns are difficult to deduce. But trust me - you have a pattern to your mistakes. Find it. Are you chronically struggling and fighting against the clock? Do you always get bogged down by the sciencey passages? Are assumption questions your worst nightmare? Are you have trouble setting up that one game (out of four)? Figure out the pattern. Fix it by referring to LSAT prep books and/or your LSAT teacher.
4. Sleep and Rest - just as diligently as you study
It's so important to rest and sleep properly. As test date quickly approaches people suddenly adopt this robot mentality - "I will eat drink and poop the LSAT!" But let's be real. You cannot suddenly become a machine and expect to 1) be happy; 2) naturalize the material; and 3) be effective.
You body and mind can only take so much LSAT. Trust me. I live, breathe, and teach this exam. I am intimately familiar with the extreme human limits of LSAT exposure. Don't make the mistake of saturating yourself with the LSAT, so much that you walk in on test date and blank out.
When you rest, resort to what fills your happiness gauge. This is important practice not only now, but for future success in law school. Students who figure out and know how to fill their happiness gauge can last longer and outdo any of his/her peers.
5. Avoid forums, blogs, and people that add to your stress
The LSAT (and law practice - for that matter) is an individual sport. It's not a team sport. No one will be taking the test for you. When it really matters it's just you and the exam. So why fret and heed those stress inducing idiots who are there just to wig you out?
I don't quite understand why and how people get to this point, but seriously, there are folks out there that simply get a kick out of freaking other folks out. Don't fall prey and become their victim.
