Manhattan Prep in person course: A great place to start

I took my first diagnostic test back in Nov 2017 and scored a 520. I decided to do a 9 session in person class with Manhattan Prep every Saturday. Ryan was an awesome instructor and the class was very collaborative. He created a great learning environment, where my classmates and I strove to help each other understand tricky questions and materials. The course provided a great framework for my GMAT studying. However, I do think most people will need to study for several months or use other services to propell them to higher scores. After Manhattan Prep I scored a 640 & 670 respectively. It wasn't until I used tutoring and TTP that I was able to get to my target score (740).
