A lot or a little?

The parents' guide to what's in this website.

Educational Value

Kids will learn about 7th- to 12th-grade state- and national-standard-related math and language arts topics. They can study U.S. history, from the pre-Columbian era to the present, and algebra, calculus, geometry, and probability. They can also answer SAT, ACT, and Advanced Placement questions and study new words, punctuation, capitalization, and literary structure and analysis in passages and poems. Kids who need more clarification can conduct virtual group study sessions. Grockit's useful exercises delve deeper than the average practice test; detailed explanations really solidify learning.

Positive Messages

Some users boast about correct answers, but most are supportive.


Most user comments are about quiz questions, but at least one we saw referenced a sexual act.


User comments seem to be generally clean, but posts appear instantly and there's no language filter to prevent swear words.


Grockit isn't filled with ads, but it's a pay-to-play site and a monthly subscription is required. Frequent plugs promote the site's private tutoring service, which also costs extra.

Drinking, Drugs & Smoking

What parents need to know

Parents need to know that Grockit only offers paid subscriptions. SAT, ACT, and other packages are $29.99 a month. Grockit also offers a three-day free trial and tutoring for $50 an hour. Is it worth it? If your kid is serious about improving test scores, Grockit's detailed offerings can definitely help. Kids can supposedly friend other users and simultaneously take quizzes together, but the functionality doesn't always seem to work; click the Add as Friend button on a user's profile, and you may be taken to a screen that says, "Something went wrong."

What's it about?

Founded in 2007 by a former Princeton Review Teacher of the Year, Grockit provides test-prep help for the SAT, ACT, and Advanced Placement exams. Kids in grades 7 to 12 also can use its Academy section to study school topics, individually or in groups of up to 30, with quiz-like sections and literary analysis and math review. They can discuss their reasoning with other students and see detailed information on correct and incorrect responses. The curriculum was designed around state and national English language arts and math standards. The site tracks user performance, shows progress, and highlights problem areas.

Is it any good?

The level of detail, combined with thorough user-performance data, can help kids identify academic strengths and weaknesses and focus on what they need to study most. Parents may want to monitor their children's time to ensure they're not connecting with a ton of strangers, but if kids access the site's interactive elements with their preexisting Facebook friends, the experience should be pretty safe. Grockit's learning can be tailored to each kid's test-taking needs, which makes the price feel less painful.

Talk to your kids about ...

  • Families can talk about completing goals. What steps can your child take to create and finish a long-term study plan?
