NIT Calicut is safe for girls but most of its rules are very regressive and gender biased. In the girls' hostel, first-year students have to seek multiple permissions for something as simple as going out to get paracetamol. The NIT Calicut girls hostel curfew starts at 7 PM for first year girls and is relaxed to 9 p.m. for seniors. The exit timings are 6 AM onwards. Everyone has to attend the daily roll calls.
To travel home, you must submit your permission form two days in advance and exit/enter the hostel between 7 PM to 6 AM. This causes a lot of inconvenience, especially if your train is scheduled at odd hours.
Hostel amenities are quite average, and just enough for survival.Traveling from Kolkata to Kozhikode is not easy, even by flight. You will get to visit home only during the summer breaks. Also, take up EP only if you are really passionate about Physics and are planning to go for higher studies. If you plan to work in the industry, the placements for EP are quite low. If you can manage with its policies and far-off location, NIT Calicut has a great learning environment and quality of education. Its campus is also really good. NIT Calicut enhances your personality and aids your growth.
Consider all these factors before making a final decision.
