After self-prep with the Manhattan book series, I was pretty excited to get a 680 on my first try. But ultimately I knew I needed to break 700 to be considered competitive for a top 20 b-school. I loved EMPOWERgmat because it did just that. I spent one month with the course, self paced and online. The videos and test tricks for success were all geared towards thinking like a test maker and being a strategic test taker. With the mindset and approach they offered, the test actually became less scary and more like a fun puzzle to solve (call me a nerd but it's true!).
I think it's a great value for the content they provide. Lot's of supplemental guides, resources, and support. And their team really cares about your success. Doesn't feel like a big prep company trying to just make money. I appreciated how personal and passionate they are the success of their students.
So if you are self-motivated and ready to take your score to the next level, DEFINITELY give it a shot!
