I’m taking Algebra 2, and I was doing okay. But then my friend told me about you guys saying it’s an easy way to boost the math mark, so I tried. I am glad I did. I did very well in my last math test. Now I use your videos as a preview of my math class as well as for test prep.

Math is always hard for me. I had math tutors before but it didn’t work out so well because they are all very busy and expensive. I tried StudyPug for your free trial and I knew I have finally found the solution. You have examples just like the ones in my Algebra exam and homework. I use you guys all the time for homework and exams.

I like studying at my own pace, especially when studying for harder courses like Algebra 2, but it seems impossible. The 24/7 access to your lessons gives me the freedom to learn in my way. I don’t have to wait for teachers at school to get help. I am now able to study at nights with my computer.
