NIT Patna is a very safe place for girls, regardless of the course you end up pursuing over here-

1. The campus has good security with guards present at all required locations. During weekends or on special occasions, the security is tightened even further.
2. The girls' hostel is located inside the campus with female security guards. The hostel wardens are friendly and treat you as a family member.
3. There are registers that you need to sign whenever moving in and out of the college/hostel. No one will ask you for your destination.
4. You can move out of the campus between 5:30 a.m. to 8:00 p.m., which is a flexible time slot. 
5. You can roam around the campus till 9:30 p.m. A delay is registered and frequent offenders are penalized.
6. For going out of the hostel for a few days, you need to get your leaves sanctioned 24 hours before.
7. Unlike popular belief, Patna city is as safe as any other Indian city. Daytime is especially safe as per my experience.
8. NIT Patna has a small campus located in the middle of the city. The surrounding areas are very populated, and there is a constant presence of Police in the entire region. On weekends, due to arti on NIT Ghat, the campus security is further tightened.

Thus, NIT Patna is pretty safe for girl students.

During your first year at NIT Patna, you’ll be sharing your room with one/two other students. You’ll get one out of the three hostels allocated for freshers. I got Kosi Hostel on the banks of Ganga. This hostel is good and you’ll enjoy your stay over there. The rooms are quite decent and the surroundings are serene.

Some facilities provided in the hostels are- 24 hours electricity, wifi, anti smoking alarms, fire rescue systems, emergency exit, mess food and purified water. 

It depends on you whether you end up hating or loving the NIT Patna hostels. But you’ll surely make some endless memories with your friends during your stay.

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.
