A computer-aided learning method and apparatus allowing a student to select an instructor from many instructors to learn a subject, and vice versa. Each user has an identifier. The apparatus can include a determinator, a search engine, a session manager, an account manager, a categorizer, and a storage medium. The determinator determines the type of user based on at least the identifier of the user. If the user is a student, the search engine identifies the instructor based on information previously stored in the storage medium regarding the instructors; the session manager manages a session between the student and the identified instructor for learning the subject; and the account manager processes an account based on the duration of the session for collecting a payment from the student to pay the instructor. If the user is an instructor, based on inputs from the instructor, the categorizer generates the instructor's profile to be identified.
