Singapore

Hi
The admissions in medicine courses in Singapore are very competitive as they are very selective. Moreover there is a 6 year bond to work in Singapore after you complete mbbs if selected. You can get all the details here.

Hi
The cost is S$5000 to S$ 20000 approximately for 6 months to 2 years Diploma course, S$ 24000 to S$55000 approximately for 2 to 4 years Bachelor Degree course and S$ 18,500 to S$ 30000 approximately for 1 to 1.5 years Master Degree Course. If you are studying 5 years Medical and Dental courses in Singapore, you might end up paying subsidised tuition fee with an obligation to work for 3 years in Singapore under The Tuition Grant Bond. This does not include cost of living and other expenses.

Hi Shruti, top business schools in Singapore are NUS, NTU and SMU. There are foreign university campuses too but recommend you to try getting into one of these three if its Singapore. Best of luck

Please go through this portal, they have a separate FAQ section too.

Remember that without adequate qualification and credentials, jobs for international students are a little difficult.

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
