User Testimonials
  • Students and parents love our math help
    But don't take our word for it…
  • Alysha Wallace
    Mother of trigonometry student, Billings, MT

    Originally, I prefer taking my son to tutoring center than learning online at home. However, my work schedule doesn't allow me to do so. So, I took the chance and joined StudyPug. Your videos are surprisingly good. My son told me that you guys are really helpful for his study, and his grades are really improving. I am glad that I have made the right choice.

  • David Coleman
    Trigonometry, Prairie High, Cedar Rapids, IA

    It is always hard for top students like me to improve grades. I'm surprised that your help is able to pull my grade up even higher. I like the tips and tricks that you provide because they are not something teachers will teach at school. That gives me an edge over other students in exams and tests.

  • Luisa Carrillo
    Trigonometry, Campbell High, Manchester, NH

    Concepts in trigonometry are tough to understand. The problem got worse as more and more questions built up. However, you are making things easy to learn. It was lucky for me to join you guys early in the term. Otherwise, I would have more problems with my study and would be hard to catch up later.
