Singapore Exam

Hi Dinesh,
Generally, you will require your academic transcripts, application fee, letters of recommendation, statement of purpose, proof of fund, valid passport, etc. More documents like test scores such as SAT or TOEFL may be required depending on the course and college.

Depends on your research interest. Ph.D admissions are quite different out there. You must contact the universities yourself and also see if they have the research area. NTU would be best for technology research work, also NUS is Singapore's best. Best of Luck
