Gives you a solid foundation- 660 to 760

I took a mock after about a month of on and off official guide practice- I got a 660 (Q43 V38). My quant fundamentals were weak since I had not done math in about 10 years.

I went through the trial versions of a few service providers. Target Test Prep seemed super intimidating at first, and I almost didn't subscribe to it. However, when I started to use it, I fell in love with the structure, the explanations and the interface. The 5 day trial with full access really allows you to take full benefit. They have an accelerated study plan versus a fullly structured one. I did the former.

For somebody with almost zero quant background, TTP was a life saver. There is an underlying 'do not panic' vibe through the entire course. The highlights, the notes and the search for keyword features were incredible. I could find problems that I needed more practice with so easily, as well as search for sub-lessons readily. The verbal section is also equally good! All of the concepts are there and the examples are very very good. I did not use any other material to prep (other than the Manhattan tests after my first official attempt, since I had exhausted my official tests).

I chose the flexible plan due to paucity of time- I really stretched myself thin in the two months and I went slightly off the course recommended path. I took my first official GMAT on November 26 and got a 640. I panicked and reached out to Scott. He said that I just need to do the fundamentals again and I'd be good. I realized as I did that and took a few Manhattan prep tests, that TTP had given me super strong fundamentals, and I just needed to calm my nerves. I decided to take it again on December 18, and I was set. My concepts were so clear that I managed a 760 (Q48 V47) even with a fever.

For anybody willing to invest some time to get better at the GMAT, I will wholly recommend TTP! It's affordable, easy to use and makes you feel as if you've got it under control.
