What our students are saying:
I love this app! I have tons of homework and it helps me get it done quickly. This app is AMAZING!!! And I love that when you ask a question it stays anonymous, which makes my mom happy :)
This has helped so much with my homework and studying for tests. Thought it wasn't going to work but it's wonderful and they not only give the answer but explain to you how to do it.
This has to be the BEST math help you can get!!! They’re fast and you'll get help right away! Never heard about an app that is as good as this one! I am really recommending it!
Got it! is great for anyone who needs help with math. It's simple and easy to use, and it’s almost always correct. I absolutely love it!
I’ve learned so much from got it! experts. What I mostly like about this app is when you ask a question they will answer you within 10 minutes. It’s so fast and helpful. I don’t know what I’d do without it!
