The cost of LSAT prep courses can vary greatly. Some companies offer free courses and many offer free trials. Some of the more expensive prep courses like The Princeton Review will cost $1,399 or more. And if you opt for private tutoring sessions, you can spend many thousands of dollars—possibly up to $10,000.  Many courses offer payment plans that permit monthly payments to make the cost more manageable. Some prep courses also offer discounts that you can take advantage of.
