National School of Business

This is the college that let you balance academic, personal & extra-curricular activities. Few Points I would like you to know.
Most experienced faculty:
If you are up for challenge in every class especially statistics/accounts related, you will enjoy it thoroughly.
Best Faculty with whom you will still be in touch after NSB as well.
You get to know different types of cultures within and outside India. You meet many people with different backgrounds.
You will get to learn management and trust me it's not because of academics. Be a part of different clubs and take up different roles, you will learn while enjoying.
Good placements:
If you have the bad habit of not reading newspaper, this might come as bad news, you have a session called BNA (Business News Analysis), where you get to present the news picked by you from the economic times (you get one every day). This improve your general knowledge, happenings in and around the world and your presentation skills.
There is no campus infrastructure for college, if you are looking for any. But, soon after joining the college that wouldn't be necessary.
Faculty & administration are very friendly. You can go to them and discuss anything and they are ready to help you out.
You don't feel like you are away from family/friends
This is based on a personal experience, you will learn what to post & what not on social media.
So overall, it is good. My suggestion, is if you know the career path for MBA and confident about the course, don't think about NSB much. Just join. But, before making any decision understand what you want in career.

Master in business administration is a two years degree course in the field of management. In India, MBA degree can be awarded by any recognized university or by a business school affiliated to any university. Post Graduate Diploma in Management (PGDM) is a two years Diploma course offered by the institutes, which are recognized by the All India Council for Technical Education (AICTE) and which are autonomous and not affiliated to any university.
It is not mandatory that a PGDM is equal to MBA. PGDM institutes accreditation by Association of Indian Universities (AIU) makes an institute's PGDM course equivalent to an MBA.
There are a large number of similarities between the curriculum of both MBA and PGDM. An MBA institute follows a fixed curriculum as it will be based on the university guidelines, which occasionally may not be aligned to industry requirements. Autonomous institutes do not follow university standards, so it is have the flexibility to align its curriculum according to industry standards and change in the business environment.
Some of the PGDM from IIMs, XLRI, etc. has more value than MBA. However, MBA from FMS - DU, IIFT, etc. have similar value as IIMs. Students are advised to choose institute based on its ranking not on nomenclature of degree.
