National University of Singapore

Hi Madhur,
NUS and NTU in Singapore are two of the best and top ranking universities in Asia and globally. Admissions are selective but to be more specific with the requirements you should have mentioned your department and level of programme if you are applying for a Bachelor degree or master degree in engineering. The fee structure accordingly varies, overall the tuition fee is not much but living expenses are high. The fee also depends on the GST rate and the Ministry of Education requirements. Some fees are subsidized and some are not. You have to write to the universities and request for the exact course fee. But here are the entire course fee, click on the appropriate links to view the figures:

The cohort at IIMs and NUS is very different in terms of diversity and experience. IIMs have almost half of their cohorts fresh out of college whereas NUS has most of the participants who have reasonable work experience. Singapore being a finance hub attracts an extraordinary exposure in term of learning which IIMs and most top B-Schools in India cannot. Also, the median CTC that is offered at NUS is way higher than that at IIMs. If we see the course fee, the MBA from NUS costs around 40-50L INR whereas the fee for the full-time MBA from IIM A, B and C costs between Rs 17 to Rs 22 lakhs. The student pedigree at IIMs A/B/C and NUS is equally impressive. CAT percentile of 99 and above and GMAT scores of 720 and above ensure only the top minds enter.
The global MBA experience, in my opinion, is what makes NUS slightly better but if someone wants to pursue MBA without much experience, IIMs are an excellent option.
