Sri Guru Nanak Dev Khalsa College was established as Sri Guru Teg Bahadur Khalsa Post-graduate (Evening) College. Later, it was made into a morning college. According to the reviews online, it is a really good college.

• It is well known that it has a very small campus but is a lively one. 
• The professors are very kind and polite. You can approach them with any of your questions but the same is not the case with the administrative people.
• Although you can’t keep your expectations high when it comes to placement cells. They recruit but not in huge numbers.

It is managed by Delhi Sikh Gurdwara Management Committee and happens to be among the few run by them. They take inspiration from the teachings of Sikh Gurus and give it all to humanity. The approach is rather holistic and provides extracurricular opportunities with state-of-the-art academia.

One of my friends graduated from this college. It is a small college with a decent crowd and a good faculty, but what really matters is if it is fulfilling your requirements. 

• If you enjoy sports, this may not be the college for you.
• In addition, the folk dance team is the best in the entire DU community.
• Guru Nanak Dev Khalsa at DU is in Dev Nagar. The neighborhood is not much appreciated by the students. 
• Since it is DU, the faculty members have years of educational experience, which is actually really helpful.
• The campus is big. But it is average when it comes to maintenance.
• The placements are also good, and students are known to perform moderately.

Overall, it is like any other college, with an average academic performance and curriculum. You can go for it as it promises a DU tag. But ultimately it is your decision.

Among PGDAV, Ramanujan College, and Guru Nanak Dev Khalsa for pursuing a B.Com, no doubt Ramanujan is the best. It is an assured college for the studies and the overall development of a student. 

Following are the things that are guaranteed in the institution:

• The location is good. Both the colleges are at prime locations situated in the most famous areas of South Delhi.
• The faculty at Ramanujan is one of the most helpful and friendly faculties one can ever encounter. They are supportive, kind, and motivating.
• The environment and overall ambiance are quite good including the buildings and the canteen.
• The classrooms of Ramanujan are far better than that of PGDAV, as the classrooms there are not even considered as average when it comes to the hygiene and maintenance part.

You should opt for Ramanujan as it is better than the PGDAV and the Guru Nanak Dev Khalsa College. It will provide a good academics and career to the student with all the required facilities.
