Why so much lower? I would chalk it up to logic games... and a sick combination of anxiety/over-confidence. I thought during the real tests that adrenaline would kick in, and I would magically understand LG the day of... Obviously not the case.
If I do re-take, I will def consider a LG tutor. My raw score in Reading Comp. was consistently 20+ but my LG was usually between 12 and 14.
In that case (and with all due respect!) I think you're approaching the problem backwards. The question isn't whether you should take the exam in February. The question is: how long will it take you to achieve good performance on logic games?
Put a plan together that will prep you to kill LSAT logic games with speed and accuracy. Use a tutor, a class, strategy books, timed practice runs, a study group, prayer... whatever works for you!
Once you have a plan, and a schedule for accomplishing the plan, then you'll know whether you can finish by February, or whether you need to wait for June.
But one way or another, fix the problem before you take that third test!
