Will this help with my child's Algebra 2 homework?

Yes. StudyPug covers every Algebra 2 strand in the Colorado Academic Standards - from rational exponents and polynomial identities to trigonometry and probability - so your child can find help for any homework problem they get stuck on.

How long are the video lessons?

Most Algebra 2 video lessons run between five and fifteen minutes, focusing on one concept at a time. Students can pause, rewind, and rewatch as many times as needed to work through tricky topics like logarithms or the unit circle.

Is there a Colorado state test for Algebra 2?

Colorado administers the CMAS assessments in Grades 3 through 8. High school students are assessed through the PSAT 9, PSAT 10, and SAT. There is no separate CMAS Algebra 2 end-of-course exam, so check with your school for any local assessments.

Can my child use StudyPug on a tablet or phone?

Yes. StudyPug works on tablets, phones, and computers, so your child can practice Algebra 2 topics like complex numbers or matrix operations at home, at school, or on the go.

Can I try StudyPug before paying?

Yes. StudyPug offers free sample lessons so you can explore the content before subscribing. All paid plans also include a 30-day money-back guarantee, so there is no risk in getting started.
