Hey Nagendra,

After the completion of the polytechnic exams, Sastra University conducts a one month course in which people who are interested in studying Btech after diploma, join. However, the student should not have any backlogs until final semester in the diploma course and with a overall percentage of 80 and above. During the last days of the course, a test is conducted on the subjects you learned in the course. Seeing your attendace percentage during the course and performace in the test, you will be called for counselling for your stream.

Good Luck.
