User Testimonials
  • Students and parents love our math help
    But don't take our word for it…
  • Carson E.

    When we saw our son's grades we looked online for a convenient, affordable and effective solution. StudyPug has been a great investment.

  • Jason G.

    This website saved my butt last semester. I am using it againthis semester. Dennis is the best online tutor... I also like that I can watch videos over and over until I really understand the concept. If you want to save time, sign up...it's only ten bucks and it saved me hours of study time. Thanks, Dennis!

  • Aaron M.
    high school student

    I get a whole library of videos that covers everything from basic to complex mathematics for a very low monthly price. Excellent videos, easy-to-understand and most of all they work. My math test results are 10 points higher than last semester.
