100 point jump to 780 in just one week

I got a 680 on my first GMAT exam in October, then proceeded to study as hard as I could in hopes of breaking the 700 barrier. After 4-5 straight practice exams getting a 680/690, I decided I needed professional. Chris was recommended to me buy a good friend (he helped her get a 730) and he did wonders in just a couple short sessions. He recognized SC as the quickest way to bump my score. We spent the majority of the time focusing on breaking down challenging SC questions that I struggled with during past practice exams and problem sets. At the very end, we touched on some CR strategy. Overall, I couldn't be happier with my score and the impact that he was able to make in such a short time. I will certainly be recommending him to anyone I know trying to increase their score ASAP.
