MyGuru

On the tutor — Priya (recommended by Mark) did an excellent job working with me to refine my quant strategy on the GMAT and her efforts, advice and suggestions yielded tangible improvements to my score, which improved from Q41 to Q49 from just over 2 – 3 weeks of prep — I enjoyed the learning process and would highly recommend making the investment and going with Priya. Totally worth it as she’s fantastic.
On MyGuru — these guys are solid– transparent on pricing and completely BS free. Highly recommend them.

I worked with MyGuru and its founder Mark to match me with a GMAT tutor. My Tutor was Chris McVety who was an actual classroom teacher for two years prior and scored well above 700 on his GMAT. His classroom skills proved to be beneficial as he Chris showed much patience with me especially in the beginning, as I came to MyGuru needing a lot of help. Chris and I spent several weeks together identifying my weak areas and coming up with a plan to strengthen them. Chris is brilliant and was able to help me look at data sufficiency questions in a totally new way. Chris shared resources with me and was flexible when it came to meeting times. He was definitely in it to see me do well. As a result I was able to improve my overall GMAT score by over 150 points.
If you are in the Boston area and need a GMAT tutor, I highly recommend MyGuru and specifically ask for Chris McVety.

I had a wonderful tutor through MyGuru in the Boston area named James Sappenfield. While I cannot speak to every individual tutor that comes through this service, James was fantastic. My focus was specifically to bring up my GRE quantitative score. James was willing to meet for several intensive sessions in the weeks leading up to my test date, at times/​locations of my choosing. Ultimately, his tutoring worked to raise my math score — and then be done with the painful GRE process forever! He was helpful, good-​humored, and extremely encouraging throughout the process.
It was nice to pay online in bulk and know that any hours I did not use would be refunded. This is an added perk of My Guru as compared to just hiring a tutor from Craigslist, for instance.
All in all, highly recommended.
