Will this help with my child's High School Algebra I homework?

Yes. StudyPug covers every Algebra I strand taught in Pennsylvania high schools, including linear equations, systems, functions, and data analysis, so students can find help for the exact topic assigned in class.

How long are the video lessons?

Most video lessons run between five and fifteen minutes. They focus on one concept at a time, so students can rewatch or pause without losing track of where they are in the material.

Is there a Pennsylvania state test for High School Algebra I?

Pennsylvania administers the PSSA through Grade 8. High school math is assessed through Keystone Exams; the Algebra I Keystone is a graduation-related assessment that students typically sit in high school.

Can my child use StudyPug on a tablet or phone?

Yes. StudyPug works on tablets, phones, and desktop computers, so your child can practice Algebra I at home, on the go, or wherever they study best.

Can I try StudyPug before paying?
