Majority subjects taught during B.Tech first year has no relation to the respective fields. Due to this syllabus design, students begin to lose interest in Engineering.
In the summer following your second semester, special exams will be conducted at NIT Patna. Through these exams you’ll get the chance to clear your first semester backlogs. One can only sit for 5 subjects at maximum during the special exams. As you have 4 backlogs, you can easily clear them during this time. There is no such mention in the grade card that you failed your exam. The difference is the session.
Normally in a grade card, the session is written as July-December. However, in your grade card it will be mentioned as Summer- Special.
Even if you don’t like your subjects, try passing in the second semester exams. If you don’t get a backlog in your second semester, you’ll receive a normal grade card for that semester and nowhere will it be mentioned that you failed in certain subjects in the previous semester.
You’ll have to get a minimum 60% (6 CGPA) overall to get your B.Tech degree from NIT Patna. So start working hard and try to maintain a decent score.
