SOLARO provides the sample of any our 1500+ classes for free, no email account required!

The SOLARO online study guide covers English language arts and mathematics from 3rd to 12th Grade for Alberta, BC, Ontario and also includes U.S. Common Core state standards.

SOLARO has great study-focused features:

~ Course-level Common Core year end practice tests for ELA and math*. All courses feature interactive question types that will be found in the new 2014–2015 digital assessments of SBAC ( and PARCC ( for this coming school year.

~ Topic-level practice tests which give you 20 questions to discover your weak spots across an entire topic.

~ Section-level practice quizzes which give you 6-question slices of a specific concept. Each section has multiple quizzes available, and no two are the same.

~ Detailed and step-by-step solutions accompany every practice question. This way, you don't just learn what you got incorrect, but how to solve those problems next time.

~ Over 300 pages of remedial lessons accompany every SOLARO class, and they are linked directly from the solutions so further help is just a tap away.

~ Built-in study tools-like flashcards and study notes-help you keep everything in one place and in sync across devices.

~ SOLARO aligns to the curriculum outcomes of all 50 U.S. states as well as the Canadian provinces of Alberta, Ontario, and British Columbia. Just tell SOLARO which state or province you live in, and it will customize itself to your regional standards. If you live outside one of these regions, please select either US Common Core or Alberta to get in-depth instruction on all the core concepts.

Using the SOLARO app requires a account.
Your free account allows you to try out our lessons and a practice quiz from the first section of the first topic in each class at no charge.

*Year end practice tests are currently available for Common Core 3rd-10th Grade ELA and Math.

Does not work on iPhone 7 with current OS

I am hoping this can be fixed as I'd really like to be able to use it. When I attempt to open the app, I get a notice that it will slow my iPhone down because the developer needs to update. I could maybe live with that, but when I click on teacher or administrator, neither will work. It pops up with "Invalid Profile: this profile is not available on this device". It lets me sign in, but I cannot use it. 😩
