The course structure is totally project based, which is designed to be covered within an hour's time. 

But in case it doesn't, then don't worry. Mentors can also extend the class duration when required. 

Apart from that 1 hour, all the concepts can be revised by accessing the online students portal, instinct queries can be solved by your mentors through call, or chats or email and concept understanding can be evaluated by working on regular after-class assignments.
