My 13 year old son loved studying with John for SSAT. SSAT is a tricky and challenging test; we've worked with a number of tutors before, but John's pace, accessibility and sense of humor clicked perfectly with my son's needs and taste. John goes through a material quickly, but thoroughly, which helps covering a lot of ground in a reasonable time and makes every session very effective. It takes a number of qualities to make a good test tutor, and John has them all. My son's score improved after just a few sessions with John, but these sessions were also enriching and fun.
We recommend him highly.
