  • My class uses Cambridge Checkpoint Mathematics 9. Would your year 9 maths lessons help?

    Certainly! Our lessons cover all the topics you will find in your textbook. We also have lessons on topics you see in other year 9 maths books such as KS3 Maths Complete Coursebook by Letts.

  • What class should I take after year 9 maths?

    Once you are comfortable with Year 8 Maths, you can move onto this course. After you mastered year 9 maths, your follow up course should be Year 10 Maths.

User Testimonials
  • Students and parents love our maths help
    But don't take our word for it…
  • Phoebe Cooper
    Parent of Year 9 student, London, UK

    My boy needs help on his maths class, but I can't send him to tutoring school. I'm glad I found StudyPug for him. They cover all the topics that we are looking for with in-depth but concise teaching videos on different topics. They also have a lot of maths practice questions available. I don't even need to get him extra exercises.

  • 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.
    high school senior

    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's only ten bucks and it saved me hours of study time. Thanks, Dennis!
