Hello All

I am changing my approach to GMAT and this time i am getting some professional help in form of videos - https://www.gmatprepnow.com/

I went through their free videos and liked the material very much. I want to purchase the full modules and then go through step by step with their learning guide. It should take me through the OG 12 (all Q's i guess) and all the Manhattan guides.

My aim is to increase my score from 510 to 600+ within 1 to 1 and a half month.

Would appreciate any expert comments.

Thanks
