I am a student in Singapore. First of all, I asked several people from Columbia Business School, who had never heard of it. If you want to major in business, such as accounting and business administration, I suggest you study kaplan in the Asia-Pacific region. Kaplan should be the most professional in the field of business teaching in private schools in Singapore, and will never lie to you like other schools. This school is connected with the government. Singapore's latest export policy is to directly explain the training of this school. Its professionalism and credibility can be imagined.
Other schools have also said what kind of university diploma you will get after finishing school, but the key is what kind of university this university is, not just what kind of school this private school is. Kaplan's affiliated universities are generally in Britain, and I know students who are about to graduate from other schools now. However, because the university is in Australia, the economic crisis has made no one work in the school, and the diploma cannot exceed three months.
So this is the only private school I recommend.
