Tutorhub
Tutorhub is a new service that provides a simple, cost-effective way to get instant homework help and revision support from a tutor. We call it ‘micro-tutoring’.
Type in a question and knowledgeable, CRB checked tutors will come back to you with offers to help. Pick a tutor and start an online, IM-based tutoring session to tackle your problem. It’s a conversation with a knowledgeable tutor, just when you need it: when you’re stuck. When you’ve finished, you contribute feedback to a proprietary tutor-rating algorithm. Charging is by the minute, so you only pay for the bits you don’t understand.
