1/5Not good for practice. Everything you write will be 100% wrong. Even if you do put the right answer
For the very first 2 problems, i put the right answer. They were very very basic problems but the grader kept telling me i was wrong. When i got the app to show me the answer, it was word for word what i wrote. I literally have screenshots of this and will be deleting this useless app. As soon as i downloaded it, they wanted me to pay for pro. So i guess getting people to pay money for a subscription is more important to this team than trying to make an app that actually works. I wonder if the code to receive my credit card info is also bugged or is it just the main function of the app thats bugged. Dont download it. Waste of time.
