To prepare for the LSAT, plan to spend at least 4-6 hours a week for at least three to four months prior to the test date. Think of your prep time as the rough equivalent of the work you’d do for a challenging 4-credit course, one in which you want to do as well as possible. The most important things you can do to prepare for the LSAT are:
Review the test format
Work through sample questions and explanations
Review at least one set of commercial preparation materials
Get copies of previously administered LSATs
Go over each practice test you take in the detail
Be physically as well as mentally prepared on the day of the test
Don’t psych yourself out of doing well
