Hii Prince!
You still haven't mentioned the subject stream you are studying in. But, let me tell you that you will usually get this information on the official website of the College. You can even ask it in the office and the datesheet is also displayed on the notice board. So, kindly keep a check on it and you will come to know the datesheet. Kindly mention more details to get more information.
Hope this helps..
Good luck!
