You should give preference to PGDAV or Motilal Nehru. These two colleges belong to the same tier and offer good academics and placements. PGDAV College placements are above average. For the 2020-21 session, more than 150 recruiters visited the campus placement. The highest CTC offered to students was INR 19.50 LPA. If you are a sports enthusiast, you should prefer PGDAV, it has excellent sports facilities. 

Matilal has a decent placement record. Students with good academics get job offers through campus placements. The highest CTC offered to the students ranges between INR 10-12 LPA. 

Among the four colleges it is recommended you go for Motilal Nehru College as it is much better in all aspects than the others mentioned.

• The whole campus is wifi enabled. 
• The computer lab has more than 100 computers and is well updated with all the necessary softwares.
• Hostel facilities are also available including basic amenities. 
• The sports ground is huge, the cultural team actively participates in singing, dancing and drama. 
• The Library has all books related to your course, Book bank is also there to take books for the whole year without paying a single penny. 
• Canteen is located at the end of the college which provides healthy and affordable meals.

Motilal is the second best college of South Campus after Shri Venkiteshwara and it boasts its infrastructure having the biggest library in the entire Delhi University. The history department is the best in Motilal.

Among the colleges mentioned above, Maitreyi College is the best option for pursuing a B.Com degree. However, it is a girl's college. The infrastructure of the college is quite good. The campus offers a decent learning environment. The area surrounding Maitrayi is neat and clean with many embassies. 

Motilal Nehru is a morning college whereas Shaheed Bhagat Singh College (SBSC) has both morning and evening colleges.

At first, you will have to decide your preference for the timings. One of my friends graduated from Motilal Nehru College (Day) and has had flatmates studying in evening colleges. According to him their routines were completely different. So, the choice completely depends on you and which time of the day you are comfortable with.

Motilal Nehru has a competent faculty, with spacious new buildings, library and good placements. They also have active societies such as Enactus, DebSoc, Archon Leadership Cell and others.

Another benefit of being in Motilal is that it is located in the South Campus and is always crowded. This crowd attracts the building of proper hangout places. Its Satya Niketan market offers good places to eat and good coaching centers.

On the other hand SBSC (E) would only give you the benefit because of its past reputation, good sports infrastructure and its proximity to Select City Walk.

Therefore make an informed decision as this will be motivated towards the shaping of your career.

Ramanujan and Shivaji are the best options. Shivaji will offer you a great campus experience compared to the other colleges mentioned here. Whereas, Ramanujan will offer great infrastructural facilities. 

You can go to Motilal Nehru if you really want to get into the south campus. However, students usually go to Ramanujan or Shivaji after making the cutoff. So, choose wisely.
