The interface is ineffective. Sometimes the same question will be asked multiple times in different ways but the system pushes me towards using one of my allotted questions to ask the questions in again. I really value having 2 to 3 versions of an answer because it helps me see different approaches to a question. They are slowly getting rid of this redundancy. The answers are not consistently helpful. Answers are typed in a way that is very difficult to read. I get the sense there is no quality assurance in terms of access. Answers written by hand are the best. Of the type of questions are good. Most types questions are illegible. Many answers are wrong- specially the ones made by Ai. Overall, about 4/10 questions a reference here are helpful. The high number of wrong questions makes me doubt all the answers I see. I’m sure it’s helpful for subjects like introduction to calculus but for advanced statistics, it is a waste of money.
