Tutoring can be very effective, of course, if you have a good tutor.
But it can get hellaciously expensive if you spend a lot of time coming to grips with the fundamentals while you are on the clock.
Now that there are finally some competent books on LSAT methodology, you should get ahold of the bibles, study them intently, and only then hire a tutor to help you with the toughest questions, and maybe some additional approaches.
Also, try and get a free test drive lesson to make certain that a) your tutor is competent and b) you are compatible, if you're going to be spending many hours together. Somebody who is brilliant but high strung or has hygiene issues is not likely to work out.
