Helen and her team provide very personalized and targeted assistance so that your child’s tutoring session is as productive as possible. They work with you and your child in a consistently supportive and attentive way. Dana W.

Mother of a High School Student

We have tried several SAT/ACT preparation services with our children over the last 4 years including self-study several group classroom approaches and individual coaching. Most will focus on expanding the amount of content the students have stuffed in their heads. This had very limited impact on test results in our experience. By far the best approach has been used by Cornerstone Prep, focusing on the test taking strategies. Helen and her Team were very effective in helping our son understand and become comfortable with how to approach the tests and spent time where he could achieve the best results. Overall, his results have been outstanding and he should be successful getting acceptances from his targeted schools. Sheryl R.
