I am not familiar at all with the U.S. system for college entrance, since I did not grow up in the U.S. I ran by chance into Harriet after my youngest son got his SAT results. She took the time to explain to both of us the meaning and the implication of his scores and designed a personalized coaching program for him, taking into account my son's individual abilities, and was flexible enough to adapt to our complicated schedules. She recommended that he should take the ACT instead.
To make a long story short my son improved his percentiles in the ACT test, jumping BIG from being in the 50% of the SAT to the top 1% of the ACT. I was not expecting that kind of improvement. It also boosted his confidence and I am sure it will help him during college.
Harriet, you rock!!!
