I had to get tutor for my son who was falling behind in first grade, not the easiest child, but I have to say I was so impressed by the professionalism and very successful creative ways our tutor came up with to get my son genuinely interested in learning ! I most definitely give A+ Tutoring an A+ in the quality of their tutors.  Thank you for helping us get through first grade and continuing to set us up for success in the coming school year!

Excellent tutoring services!! I've been using A+ tutoring for about 7 years now.
I first started with my older son, when he was in middle school struggling with English and Writing. He is now a freshman in college doing very well. I am now using them for my younger son, who is a sophomore in high school. Roman has been a class act, and is very knowledgeable when it comes to the school system. He has been hands on from the start. When my son started to struggle in Math, I knew exactly who to call with my questions and concerns. I have tried to use other tutors in the past, but A+ tutoring is the company that I have seen real improvements with.

Excellent tutoring service. I used it with my son for in person tutoring for SAT and he's in top school in University of Florida now.
My daughter is doing remote studying as we are now and Florida and she boosted her score by 130 points 3 months.
I am grateful to have such wonderful resource for my kid's SAT success.
Highly recommend.

We are so pleased we hired A+ tutoring for our daughter who was gearing up for the SAT that she took a few weeks ago. We first met with Roman who was extremely knowledgeable and answered all our questions regarding taking the SAT vs ACT and the college application process. After meeting our daughter, he put us with the tutor, Cindy, who is outstanding! My daughter instantly bonded with her and she was able to break down challenging SAT practice problems with thorough explanations. We worked with Cindy for two months and the results paid off!

Terrific tutoring service. I'm a parent of twins who have their individual strengths and weaknesses . Our tutor  (Amy) was able to work with both individually and provide for a tailored program for each kid. Amy was terrific. She was engaging and patient, and most importantly our kids showed real progress in math and writing. The company is organized, professional, and responsive.

My son needed help with his math class. He was very lost with everything and after just a few weeks of tutoring, he ended up enjoying math more, caught up with all his work, and learned a lot. Will definitely come back to get the extra boost of help.
