Among all three colleges, Khalsa College is better since it has good infrastructure and better faculties. It is also a co-ed college and the crowd at SGTB Khalsa College is much better than Daulat Ram College.

It’s always better to choose an institute near your home. You can save the time you will need to spend during travel otherwise. If distance isn’t an issue for you, you can choose Jesus and Mary College. 

Whether you should opt for MnC at IIT Delhi or B.Math at ISI Bangalore depends on what you want from your graduation and your career prospects.

Academically both institutes are excellent and none is better than the other. So my answer entails the drastic difference in the curriculum and scope of the two programs.

Bachelor of Mathematics, ISI Bengaluru

This program has high-tech mathematical stuff and purely focuses on Mathematics. The Institute is smaller than IIT Delhi and ideal for those who have a single passion in life, Maths. The coursework consists of abstract algebra, analysis, probability theory, and so on. Additionally, it has compulsory courses in Statistics, Probability, and Physics as well. Although it offers some CS courses also, the program does not focus on Computer Science much.

Math and Computing (MnC), IIT Delhi

The curriculum of the MnC program is more inclined toward computer science than Mathematics. The program focuses more on applied mathematics, rather than pure mathematics. As a result, graduates from this course can start jobs earlier than those from ISI.

In a nutshell, if you are willing to go for higher education and research in mathematics, then ISI should be your goal. If you are a person interested in the practical application of concepts and want to eventually be employed in a company, then IIT Delhi is the best place for you.

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.

Among Dyal Singh College (DSC) (morning) and Rajdhani College (morning), students usually prefer DSC rather than Rajdhani. This is due to the following reasons:

• Mathematics at DSC is said to be the best in Delhi.
• They have faculty members with more than 40 years of educational experience.
• They are cooperative and will guide you through the subject's tougher portions.
• The overall infrastructure and maintenance of the campus has improved a lot.
• The college canteen provides healthy food items at a reasonable price.
• Here you will be learning amongst some of the best minds.
• The only thing that needs some improvement is the internet connection. The whole campus is wifi enabled but has several connectivity issues.
• The placement is also good. They have a dedicated placement cell as well.

The science group in DSC is considered to be one of the best. They provide proper training and exposure which will ultimately help your career.

Both Ramjas College and Kirori Mal College are quite reputed colleges. There are no such parameters to differentiate between these two. Both of these two institutes have good faculty bases. You will also get decent facilities to learn at these colleges. 

The only significant factor that can be mentioned is that Kirori Mal has a NAAC A+ accreditation with a better grade as compared to Ramjas. However, it’s not wise to compare these two institutes based on grade. You will have decent opportunities at both. So, you can opt for any of these two based on your convenience. 

Both institutes are relatively new and enjoy a similar status and brand value in the education world. IIT Palakkad is a new IIT while IIT Dhanbad although an old institution has recently been given the IIT title. So that leaves us with preference as the major factor in determining which institute is the right one for you.

MNC is a blend of both Math and Computing concepts and is often very rigorous. The mathematical proofs and theorems form a major part of the curriculum and CS comprises just a minor portion of it. Unless you are a math lover or are genuinely interested in it, this branch might be very challenging for you as the concepts are very advanced and nothing like what you studied before. CSE on the other hand is an evergreen branch with broad prospects. 

Moreover, the faculty of IIT Palakkad are from IITM also thus improving the quality of education offered. The infrastructure is excellent with great accommodation facilities.
