Christopher is a miracle worker. I hired him at close to the last minute to help my daughter prepare for the SSAT test, which was a last minute thing and left her only 2 weeks to prepare. I was concerned because she'd just come out of a gifted math class but was very confused and I was helpless in this new era of common core. In addition to an incredible manner with her, he prepared and gave her the confidence she needed to get 98-99th percentiles on the test. He was happy to go over any subject. Now that she's in a private middle school, we keep seeing Christopher once a week so she always has a helpful and supportive ear for the things mom and dad are useless at. Thanks so much Christopher!
