Singapore

Dear Aman, criteria differs with universities. Generally applicants must have a very good academic record. SAT must be taken. TOEFL or IELTS might be required though it is not mandatory. Always visit university websites for exact details.
Best Wishes

Hi Priya,
Varies with what you want to study and which university. Singapore is one of the most affordable study abroad destination. Tuition fees overall may range from Rs. 12 Lakhs to Rs. 30 Lakhs a year. MBA programs are more expensive. You may refer to the list of options below

still a lot of scope in town and small cities

Hi Neha,
Your IELTS is low. You would need a minimum of 6.5 to get into decent universities. You would also need GRE for Canada, Singapore and Germany. For Germany, the academic score is too low. Would recommend you to look for Australian Universities but be prepared to re-write your IELTS.

SMU is the place for MBA and details for all the requirements are here.

Try for NUS,NTU and SMU if you are looking for career prospects and recognition.

There is no difference except the infrastructure, teaching methodology, exposure, assessments, stress-levels, etc., Hope this helps. Thanks!

Hi Lokesh,
Singapore's NTU has a course which costs about 15 lakhs in tuition for one year. USA has many options but would be costlier than Singapore.

Hi Sagar,
Studying in Singapore from a good university would increase your chances of finding permanent employment. Continued employment is necessary for growth.

Hello,
Start researching on the universities. You can check QS world ranking to know about the top or best universities in these countries. Visit their websites and check the individual university admission requirements. You must take GRE and TOEFL or IELTS and to get into the top competitive universities you must score high. At this moment start your research.
