Hey, HKrustofsky, what LSAT prep course did you take to get the 174?
I took a 3-day local prep class 2 years ago but it was pretty worthless. I got a 167 on my diagnostic so I think I'm just really lucky that the few strengths I have are a good match for the exam.
Edit: If you're prepping now, IMO, nothing beats practice as the absolute best way to prepare. In addition to doing individual problems and sections, I took over 20 timed full (5 sections)practice exams. Good luck to you.
