Given Courses on this platform is limited of time and quantity of free course coupons by the Tutors.

So, take the courses as soon as possible, as most of the course coupons have 2 to 3 days of validity to enroll them for free, once you enroll them, course are free for you till the lifetime.

In case you didn't enroll the course with in it's Coupon Validity Period, it will become PAID again.

(If you don't want to enroll the course, don't enroll them just leave it for others)
