Hello,

Alright. So the age old attendance TRUMP CARD has been thrown at you and you have no answer? ALRIGHT!!! First of all lets understand a few things. There are few colleges such as ILS Law college which have extremely strict attendance policies and if you do not fulfill the attendance, they wont even give you the admit card to write exams. Now coming to your case, you have not mentioned as to which college you belong. If your college always had the reputation of being very strict in attendance and yet you took admission in college and yet you did not attend the college, nothing can be done now but if you have taken  admission in some college in which attendance is not so strict and you are aware of it, then you may write an apology letter or give some medical certificate(BE TRUTHFUL IN LIFE, NEVER LIE), or talk to principal as to why your attendance is so low. You may appear for exams only if you have admit card in your hand. As far as cancelling your admission is concerned, since you are in your 1st year, college might give you a warning regarding your attendance and cancellation of admission seems to be not on page. Since you have zero attendance, its difficult to predict anything. Talking to college principal would be advisable.

Hope this helps.
