Read full description

Feynman is a tech startup company based in Alexandria, Egypt. Feynman's main core is providing educational help for college students to understand academic/non-academic subjects. The main use of the application is that students who need help in any academic or non-academic subjects can smoothly pick one of Feynman's tutors staff and arrange a tutoring session. Initially, Feynman has gathered a team of tutors to provide the service. Our current tutors team is a team of undergraduate students who are enrolled in normal universities in Egypt. What defines our current/new tutors the best is that they are students/experts who are very passionate about helping other students, concerned in contributing to the creation of a unique way of teaching using the Feynman technique. The meetings would happen in places that are contracted with Feynman. Student have two session nature options. The first one is called a "quick help" session, which is only obligated to students who have quick topic to learn or quick question to be answered. The second option is called a scheduled session where students can learn bigger topics and ask more advanced problems/questions. In addition, the application has a feature called ‘Join’. This feature is provided for students who want to join an already booked sessions; those session are booked by other users. If the tutor accepts the joining request, then the student is welcome to join the session
