It's helped me a lot so far! I'm an A-B student, a bit of a perfectionist, so I'd get upset over B's. It mainly helped me with Math, English, and Science. I'm not one to need help with History or anything. I've gotten fewer B's in math, more A's. My A's in ela raised from 90 to 95-100. Science went from occasional B's to mainly A's. And it helped me a lot when it wasn't the type to give the answer instantly. It tries to help you actually learn the material before getting the answer. No problems.

I love this app, I used to use it 24/7 for help on my homework and it would be right at least 90% of the time! But recently, they've added an update where if you aren't paying for premium, you only get about 2 tickets per day... I get that they want to make money, but they should at least give us more tickets, or give an option to watch an ad for more.

I have never written a review before, but this needed a warning label on it. I would take photos of my statistics homework, and 80% of the time, it was always wrong. I would ask AI to recalculate, and they would just give me another wrong answer. So far, I'm better off working alone for hours than getting frustrated over a computer...😔
