Joy H.

I was tutored by Mr. Okoro for AP Physics 1, both AP Physics C exams, and AP Chemistry, and through his help, I was able to achieve the scores I wanted. I felt that Mr. Okoro was a very effective teacher - his lessons were very concise. He would often cover concepts, draw diagrams, then give a few practice problems to test understanding. I would definitely recommend Mr. Okoro to anyone looking for tutoring, not only for improving AP scores but for improving understanding of a subject.

Rahul N.

We highly recommend Michael's services. We found him to be flexible and accommodating, allowing us to adjust our schedule up and down based on our son's needs. He was also able to break down difficult concepts in a way that was effective to our son's learning style. Our son was able to successfully complete the freshman geometry course with Michael's support.
