@Saira & mishalc: Many of your questions would be answered by reading the appropriate sections of the latest prospectus at Prospectus .

Summer vacations are for one and a half month to maximum two months. In 1st and 2nd year no vacations would be granted if you fail in any of your stages, because it is during that time, you will have to reappear in those failed stages and clear them.

Winter vacations are for 1 week. Most of the students go abroad or to America for electives during summer vacations.

Do not be scared by the frequent use of the term fail in my posts, it is there just to make sure that you know what would be the consequences for it. Also Stress can lead to decreased concentration, short term memory, rational thought and inhibition. So you should invest some time in stress management to keep those important things going.
