When I was preparing for the Oct LSAT, I hired a private tutor from testmaster. The private tutor was pretty helpful for me to improve my PT score from low 160 to nearly 170.
I plan on taking Dec LSAT and the tutor suggested me to buy the testmaster online package, saying if I study their material, I will reach upper 170s in the real test. He seemed to make a genuine suggestion, but I always suspect that prep course is for beginners. I don't know whether I should buy their online package to study for Dec.

Does anyone here had experience with their online package? Would it be helpful for people who are prepping at high 160s?

I took TM live courses, and they helped me improve my score from lower 150s to mid-160s. Ever since I've been studying on my own, doing PT one after one and now I'm around 170. I don't think any test prep company can help you from upper 160 to 170+.
But people keep telling me 7sage is a good idea.

Thanks for your replies. So no online course for me I guess. I will continue to do self-study with tutoring sessions sometimes.
