Ranks don't always depict how perfect a university is Your choice depends on a lot of things - course, networking, opportunities, etc. Plus, US offers a higher range of options to students Whereas Singapore only has 4-6 well-known universities

You can check out these universities- Harvard University Stanford University Johns Hopkins University Massachusetts Institute of Technology University of California, San Francisco University of California, Los Angeles

6.5 overall and 6 in each individual band

Depends on a lot of factors- Weather- Switzerland is colder Language- The subject you choose might not be taught in English, but French (depends on the course and university you choose) Cost- Switzerland is usually more expensive And more

I'd say Canada is much friendlier and wants to retain international talent But it also depends...I mean the quality of education is also really good in the US Depends on your preferences

You can also consider countries where the tuition fee is less but the ROI is good, like Canada or the Netherlands.

Another exam you can give for English proficiency is PTE
