It's my advice to try colleges near your locality.

Anirban, it is really difficult to get admission in Eco Hons. without maths. Economics is a subject which deals with a lot of mathematics. So in my view, please go for another course. There are many courses which are better than Eco Hons. And personally, if by chance you get Eco Hons. without maths, it will become very difficult for you to cope up with the mathematical concepts in Eco Hons.
And in future, it is much better to not opt for Eco Hons. than suffer failure. Go for another course.

It depends on your best four %age of 12th.
DU conducts admission through the merit-based system.
Usually, the cut-offs for Economics Hons. vary from 93-99% in DU.
Every DU college has a different cut-off for different courses.

B.Com and B.A. Eco Honors are the most famous courses in DU and it is natural that they have high cut-offs.
So it depends on the 2018 cut off of DU. Every DU college varies in cut off. You may get an idea from the 2017 cut-off.
Please refer the below-given link of 2017 cut-offs of DU-

Cafeteria system allows you to opt for modules of your choice. While doing some language courses, you could opt for Phonetics, Linguistics, etc. in addition to the core courses prescribed. Thus, you have the freedom to opt for modules of your choice instead of getting bogged down to prescribed courses like in traditional universities.
Once you get a seat, there will be a good briefing by the authorities about the advantages of each course and the freedom of selecting the units. The teachers at EFLU are mostly very student friendly. You could also take the help of senior students who are in MA and PhD.
Important issue, get a seat.
