Yep. Definitely helps solve any queries you may have. Also during exams it helps you prepare with others and go through stuff you may have missed, and then gauge your performance right after the exam so that you can get over it faster and prep for the next one.
definitely has helped, the predictions peoe have here on the student room for sociology as were 100% correct and also people shared their revision materials and sources and helped with topics I was struggling with and even gave me essay structures etc!
