Course would be accessible for the duration as given in the table below. Do note that we can give you one extension if you so desire at the end of the validity term.

Course	Duration
Advance C & UNIX Internals	12 Months
C++ & Object Oriented Programming	8 Months
Design Patterns	8 Months

One other benefit of taking more than one course is that the duration of the courses is clubbed together e.g. if you take Advanced C & UNIX Internals and C++ & Object Oriented Programming Courses, both the courses are available now for 20 Months. If you take design patterns too, then the validity is extended for all three courses for 28 Months.
