Ok, something that improved my score significantly on both my practice tests for LSAT (and eventually the bar exam): You have to start analyzing what percentage of questions you are getting correct at the beginning of the test and at the end of the test.
This form of test taking is almost like running a marathon… at first you are doing just fine, but then you get tired and you slow down.
In the case of taking these grueling and stressful tests it is only natural that you will mentally begin to get tired. If you analyze your correct and incorrect answers closely you will find that you will get more questions incorrect during the second half of the test vs. the first half of the test.
Most likely in preparing for the LSAT (or bar exam) you will need to improve your mental
endurance. How do you improve your mental endurance?
1) Slowly increase the quantity of questions you do for practice (ie when you are not taking a full test) don’t just work on 25 questions, slowly increase it to 30, then 35, and so on.
2) When you take practice tests do not immediately stop your practicing… add another section with no break. (Think of a marathon runner slowly increasing distances.)
3) Studies have shown that caffeine can increase mental capacity for short periods of time. When you take your test have a cup of coffee or other caffeinated beverage ready for the half way mark of the test (or when 3/4 of the test is completed).
Break down your scores to see if endurance is a weakness for you, read some more about the
LSAT at the below link, and start training for endurance (increasing slowly).
I hope this helps!
