Chegg is HORRIBLE. I would say you have a 50/50 chance of finding anything related to what you're working on. Then it's a 50/50 chance that the answer is explained and correct, most of the time it's just an answer without explanation. Then it's another 50/50 chance that you can read what is being done. THEN when you're so fed up with everything and you cancel, they charge you again and won't issue a refund. I really don't like this service. I will make sure everyone knows.
