Singapore's official languages are English, Malay, Mandarin, and Tamil. In addition to these, you can expect to hear a variety of other languages spoken around the country.
It is very popular for colleges to provide English classes. If you want to study in a language other than your native tongue, you will very certainly be required to show proof of your language ability. If you don't fulfill the minimum requirements, you might be able to benefit from a language course.
Even if you can study in English, living in Singapore provides an excellent opportunity to acquire multiple languages. Practicing with locals and other students is an excellent approach to do so. Having a second language is a valuable ability to have on your CV or resume.
