Algebra 2 · In studio

I was absolutely amazed by Dr. B's attention to detail and patience as he took me from basic arithmetic and (failing Frederick Community College's placement test) to Algebra 2 and scoring high enough on the test to pass into college level math on my 2nd try! I have never been good at math, and my Criminal Justice major only required 1 math class. However I still needed to pass the placement test into college level math...so I could satisfy my degree. Dr. B' is committed to each of his students and genuinely cares about their success in life. Not only is he good at the subject matter of math (all kinds), but good at teaching it and explaining the theories behind what makes numbers work.

AP Calculus · In studio

I cannot say "Thank You" enough to Dr. B for helping my son John get back on top in math and AP math courses. He got a good SAT math score, 2 big scholarships, accepted to a good college this fall...If you have an opportunity to help your son or daughter. Please, do not wait, they need help ASAP. Dr. B helped my son about 1 and 1/2 year (2-4 hours a week).
