I ran by chance into Harriet after my youngest son got his SAT results. She took the time to explain 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 king of improvement. It also boosted his confidence and I am sure it will help him during college.

From our very first visit with Harriet I was very impressed with her techniques.  She worked with my daughter closely to understand her goals.  Harriet then developed a personalized tutoring program and schedule to fit my daughter's needs.  We have worked with other group tutoring programs in the DC area with my older child but now I have a great appreciation for the benefits of working one on one with a dedicated tutor.  I really can't say enough about Harriet and her team. And in the end, the test results were amazing!

I could not be happier with the results that Harriet and the Team at Breakthrough Test prep helped my son achieve. He has already been through months of tutoring at another firm and did not preform well on the ACT. Harriett laid out a plan to help him be successful. his score went up 7 points in the ACT which is a difference-maker in the college application process. Additionally, the skills around Reading that he now has will help him be more successful in college. I highly recommend Breakthrough Test Prep!
