Among Sri Venkateswara and Ramjas, the former is the better option for a B.Com program. 

The administration at Venky is quite good. It has many active societies. Everything at the institute is online. You can easily get your admit cards or pay your fees. It also offers better academics and faculties. 

It is suggested that you go for Sri Venkateswara College (SVC) or Sri Guru Gobind Singh College of Commerce (SGGSCC), as both colleges are famous for their commerce department. 

They have the best, most experienced faculty with some professors having 15-20 years of educational experience. You will have opportunities to take part in extracurricular activities through clubs and societies. SVC also has the best placement opportunities and has the advantage of being in Satya Niketan, the best college of south campus.

Therefore, your first choice or preference should be either SVC or SGGSCC, followed by Ramjas college.

Among Deen Dayal Upadhyaya College (DDUC) or Sri Venkateswara College (SVC) it will be better if you go for SVC.

Here are some reasons:

• SVC is located in the South campus and is considered one of the best colleges under DU.
• DDUC is a much newer establishment and has not yet reached SVCs level of popularity.
• SVC is also known for its brand which gives an upper hand during off campus placements.
• The Mathematics department in SVC is the best. DDUC is not even close to its standard.
• SVC has a well experienced and respected faculty.
• The crowd at SVC is also very competitive, which maintains a proper educational atmosphere in the campus.

Therefore, it is suggested you go for SVC as it will provide you with better exposure and opportunities.

I know people from both JMC and Venky. Based on the things I heard from them, I will say Venky is definitely a better option for doing a B.Sc (Hons) in Mathematics. Here is why.

• Faculty - Venky has one of the best faculty bases in the whole university. The teachers are well-experienced and cooperative.
• Infrastructure - The infrastructure of the institute is great. There is a foyer, ICT lab, auditorium, and a well-equipped Maths department. 
• Library - The library has a great collection of books. 
• Fest - Exponents is the fest for the Maths department. You will get to meet other Math scholars in this fest. Other than that, there is the annual fest Nexus.

Considering all these factors, it is safe to say that Venky is definitely a better option.

Both colleges have their fair share of similarities and dissimilarities. Let me provide some facts about both of them, analyzing which you can move ahead with your decision.

• Both the colleges are excellent in their own way.
• The infrastructure of Science blocks is very good in both the colleges.
• Both colleges have diverse cultural societies. Players -The Dramatics Society of KMC, is one of the best in DU

• KMC, being almost in the centre of North Campus, has its own perks. It is said to have better placements than South Campus colleges.
