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

Yes. StudyPug covers the topics Illinois 3rd graders work on in class. Your child can look up any concept, follow a step-by-step explanation, and work through practice problems to finish homework with confidence.

How are the science lessons structured on StudyPug?

Each lesson uses video instruction paired with practice problems and worked examples. Your child can pause and rewatch any section, then test their understanding with guided questions before moving on to the next topic.

Is there a state science test for Grade 3 in Illinois?

Illinois administers the Illinois Science Assessment (ISA), but it is not given in Grade 3. The ISA is typically given in grades 5, 8, and high school, so 3rd graders are not assessed by a statewide science exam.

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 or on the go. The lessons and practice problems are fully accessible from any modern device with an internet connection.

Can I try StudyPug before paying?

Yes. StudyPug offers free sample lessons so you can see the content before committing. There is also a 30-day money-back guarantee, so you can sign up with confidence and get a refund if it is not the right fit.
