What is the difference between the north and south campus colleges of DU?

There is no discernible difference.

1-The faculty levels on both campuses are the same. Teachers on the south campus are more helpful and friendly, but there are a few good teachers on the north campus as well.

2-When it comes to PG or food, the South campus is far too cheap. In the south, one can find very good affordable accommodation. North is a little pricey because there are too many colleges, which increases the demand for goods and pgs, and thus prices.

3-The crowd in each college is nearly mixed and uniform. Although the north campus receives more applications from students from UP, Bihar, Haryana, and Rajasthan because it is overrated and hyped among people, all mostly SC, ST, and OBC, sports quota, and ECA quota students go there if they get it anyhow. 

4-Colleges do not provide degrees; DU does. So, regardless of which college you attend, you will receive the same degree.

5-Placements- this is an extremely important factor. The majority of placements are reserved for Bcom and Economics Honours students. Placements are available at LSR, SRCC, Hindu, Venky, Hansraj, KMC, and Ramjas, but only for Bcom or Economics students. Other department students may be offered the internship, but the pay is insufficient.

6- Restrooms and drinking water- The restrooms in each college are clean and well-maintained. Clean and sanitary. However, if you drink a lot of water, you should only go to North Campus if you can buy a bottle for each day because the water there is too salty. 

There is no distinguishable difference between the two campuses. So choose a college that is easy to get to, as the metro has raised its fares, and where PG, hostels, and flats are reasonably priced, as you will be spending three years there.
