The difference in the graduation dates just reflect my attempt to gain some hands on practical knowledge in order to develope a deeper understanding. While its is convetional to pursue a PG immediately after completion of one's UG i took some time off to gain a non educational perspective to the subject. During this tenure I also spent a substatial amount of time learning some other  arts and pursuing my intersets and hobbies in order to give myself a well deserved break after spending some gruelling hours doing my course work
