Traditional tutoring is too expensive and inconvenient. With Rayku, we want to cut the price by 70% and offer it at micro tutoring rates of ~20 cents per minute, so that it is bite-sized enough to be accessible to anyone. We do this through a unique peer-to-peer online tutoring model. When students have questions, they are matched with members most qualified to help, and connected immediately over a live shared whiteboard for a visual, real-time explanation through conversation. is a peer-to-peer micro tutoring site that lets students share & ask for academic help in real time.
