We were assigned Andrew Carr to help prepare our son for the SAT test. He had taken the test two times previously and had scored ok, but not great. He only had one more opportunity to take it before his college applications were due. Andrew was wonderful. He met with our son five times for 1 1/2 hrs. each session. Most of the time he went over and really made sure our son had a clear understanding of what they had just covered. This morning we received the new test scores and they were up by 200 pts. We were thrilled!! I highly recommend Andrew and Boston Tutoring Services.
