Will this help with my child's 3rd grade science homework?

Yes. StudyPug covers the physical science, life science, and earth and space science topics your child is working on in class, so they can find help for specific homework questions any time.

How long are the video lessons?

Most video lessons run between 5 and 15 minutes, which keeps things focused and easy for 3rd graders to follow. Your child can pause, rewind, and rewatch any lesson as many times as needed.

Is there a state science test for 3rd grade in Oklahoma?

Oklahoma administers the OSTP Science assessment, but the tested grades are 5 and 8 at the elementary and middle levels. Grade 3 is not a tested year, so no state science exam is scheduled for 3rd graders.

Can my child use StudyPug on a tablet or phone?

Yes. StudyPug works on tablets, phones, and computers, so your child can study at home, on the go, or anywhere they have an internet connection.

Can I try StudyPug before paying?

You can access free sample lessons right away with no payment required. Every subscription also comes with a 30-day money-back guarantee, so there is no risk in getting started.
