Rachel McCarthy
Third year maths student, Cork, Ireland

I was struggling with my study for Junior Cert maths, and so I went online for help. However, most of the maths websites aren't really helpful. And then, I found Study Pug. I can find everything I need for Junior Cert and more. Now, I am using StudyPug to study and prepare for all my maths quizzes and exams.

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

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!
