Extremely Helpful Course.
Mark Porath does an excellent job of delivering the ManhattanGMAT material. This course supplies students with all of the tools necessary to post a 700+ score. By studying and staying on top of the materials, I was able to exceed my target score of 700 and now am applying to top graduate schools.
I highly recommend this course for anyone who is interested in scoring extremely well on this test and having doors open as a result.
