Understand The LSAT
Again, the LSAT is a practice makes perfect kind of test - any book or course guaranteeing you a perfect score without you putting in time and effort is a scam.
Few people simply pick up the LSAT one day and ace it - the LSAT requires practice.
Similarly, you cannot cram for the LSAT – getting good at the LSAT doesn’t happen overnight - developing good techniques and incorporating “LSAT-thinking” into your own way of thinking is a skill and is developed gradually through practice and repetition.
