Nanyang Technological University

As you have not mentioned which graduation programme you are going to apply, I will add both *MS or M.Engineering: There are 2 types of Master's degree programmes (a) MS by research work (b) MS by coursework. Coursework is more like training to get a job, it includes not much research experience. MS research work is more like getting yourself immersed in research and thesis. Here, your lab or research-oriented works are more than coursework basis studies. But with GATE score only one can apply for MS research work in both NUS and NTU and coursework programme needs no GATE or GRE score but if the no. of applicants are huge they will shortlist on the basis of GRE scores.
* Ph.D: There are no such divisions for Ph.D. But there are various types of programs in Ph.D like NTU-TUM and NTU Home University.

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:
