The GMAT is a hard exam you take after university if you want to go to business school — the kind of school that trains people for management and for an MBA. It is not a test of whether you already know how to run a company. It tries to see how you handle numbers, written English, and tricky problems under time pressure. Schools, especially in the United States but also in many other countries, use the score to help decide who to accept. In Taiwan you will hear students say ‘I’m taking the GMAT’ in the same breath as TOEFL or IELTS; those English tests show you can study in English, while the GMAT is the business-school gate. Though actually, not every master’s in business asks for it now — some schools take the GRE instead, or look more at work experience — but the name still means ‘the big exam for business school’. You sit it on a computer, and people talk about their score the way others talk about a university entrance exam.
