The cost of a monthly subscription plan is $35 and the annual subscription plan is $240, which is less than the cost of traditional tutoring. One nice thing is that this website does not auto-renew your subscription, so you don’t have to worry about canceling. You can pay either through credit card or PayPal. Another advantage is that all instructors are university professors, while the experience of local math and science tutors can vary greatly.

One of the main advantages of this website is that you receive unlimited access to all their videos and examples, not just the subject you were interested in when you subscribed. You also get access to other student comments and questions and to the messaging system. The comments sections are visible only after you subscribe and are closely moderated by professors.
