This is suggested as a general, fundamental approach.  Each person should modify this regimen to meet their individual needs.

The LSAT is a "skills based" test where practice and review of your specific answers make a difference. Go for mastery and then speed. You want to reach your best level a week before the test.  

This will happen through incremental gains from consistent short term practice sessions - an hour or so each day on problem sets and sections.

Spend some time on the reading comprehension and the writing sections - all sections are about logic - and it is important to approach these two sections with that mind set. 

Take a complete practice test once or twice each week, under test conditions, perhaps in a library early in the morning for the complete, uninterrupted time.  Stamina counts. Your answers in the third hour are as important as your answers in the first.

You want to review through the last week until Thursday, then eat and sleep normally through Saturday morning of the test.

On the actual test, try to match your best speed and tactics.  This is the most effective approach without the stress of trying to outperform your own successful strategy.

Focus on your own performance; how fast or slow anyone else in the room is going is irrelevant to your performance.  Focus on the proctor and your own work.  No one in the room knows more about how you should take the test than you do.

Dress comfortably and in layers; follow the rules exactly in terms of what you can bring.

Arrive early. If possible visit the test center so that you know where it is and you can get familiar with the surroundings.

As you prepare, spend some time as you begin your sessions remembering your past academic successes; as you end your sessions think of what you learned and that you are progressively becoming more familiar and effective with the test.
