ISI Kolkata does not provide a B.Math program. The majority of B.Stat students return for M.Stat while some people join CMI, TIFR, IIM, and other such organizations.
M.Stat employees earn an average of 16–17 LPA, and many of them attend prestigious US graduate institutions. There are no fees for the entire program, and a stipend is provided. So, if you're looking for a career here, your future is bright.
The BSc (Maths) entrance exam is BHU is one of the easiest exams. You can score fairly good marks by just going through your 12th-grade Maths, Physics, and Chemistry books. Study Chemistry from NCERT book. A thorough study of the following chapters will get you good marks:
Biomolecule
Polymer
Animes
Chemistry in everyday life
The questions in the entrance exam are mostly based on direct concepts or formulas.
As far as the number of marks necessary is concerned, there is no fixed digit. But at least attempt 70 questions without mistakes. This means you need to score at least 210 marks out of 450. However, this number keeps changing based on the pattern of the question paper.
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.
Both B.Stat and B.Math are different courses being offered at different campuses at ISI Kolkata and ISI Bangalore respectively. There are only a few common subjects in both courses.
The choice ultimately depends on your choice and interest. You can go through the syllabus of both courses and understand the topics. Find whichever interests you, you can choose to be research-oriented like B.math students or go for M.stat or other courses, if you choose so.
You can apply for only 1 course because the institute conducts the entrance of both courses at the same time and day. You will be able to appear for only one of them.
