Exam pattern is semester wise system. 40% of ur total marks come from internal tests and the rest is through semester end exams. from what I understood from schedule, one sem ends in November or in the first week of December. Holidays are usually given like in school days. You will have three internal exams called mid term exams out of which 2 of your better scoring marks will be considered. In first year, students of all batches have same curriculum. There are many events and fests around the year so, watch out an have fun.
