Overwhelmed! 650 to 700+ with prep courses/tutors etc in three weeks?

Hi everyone!

I've seen so many posts on the forum asking for similar help but I find it a bit overwhelming to be scrolling through posts upon posts, some feel relevant and others not at all.

I've done the GMAT three times already (second one I cancelled). Last score was 650, which was a 10 points increase from the first one. I have been scoring around 650-710 on my practice tests with Kaplan and I also had a Kaplan tutor for about 15hrs of lessons. I'm scoring around 40-47 on my Quant and 32-40 on my Verbal. I know that if I manage to do both section well on the same test, I can cross the 700 mark, but I find my scores to be too volatile. I want to just solidify my score above 700, preferably around the 730 mark and am available full time to work on this the next few weeks.

After my tutor lessons, the tutor recommended that I do practice questions and carefully review to develop the "GMAT instinct" so I have been spending a lot of time on doing questions and thoroughly reviewing them. I have a good grasp of most of the concepts and cannot really pin point a pain point. However, I am not seeing any improvement. Application deadlines are coming up and I would like to get some thoughts on which prep company/material/courses/strategy I should go with for the next three weeks?

From the forum I've understood that e-GMAT is good for verbal and others say that Math Revolution is good for quant. I'm not really sure what I need and somehow feel that after watching hours of hours of Kaplan videos, I'm skeptical that watching more videos from someone else would be helpful, but maybe I'm wrong?

Everyone keeps saying that GMAT is the most predictable component of a B school application but right now, I feel it's what keeping me from the top schools

Any advice and guidance would be helpful - also open to signing up for additional courses and tutor sessions, but I have three weeks and want to make sure it's worth my time!

Thanks a lot!
