DYNAMITE
@life changer - great questions! I think you will definitely benefit from the knewton course. It is primarily what I used to prepare. Their strategies are great. Don't bother paying for the live course... As I said, I would recommend using the
mgmat sc guide after you do the knew ton sc. It covers some stuff that knewton doesn't and isnmore GMAT appropriate!
I'm confident if you do these things you'll push up past a 40! Let me know if I can be of more help

That's precisely what i wanted to know...How relevant and effective is the course material of knewton?..being a Nonnative speaker, i am inclined towards a course that can prep up my verbal score..
Thanks for such a quick and informative response..kudos
