MIT is a famous American university in Cambridge, Massachusetts. The letters stand for Massachusetts Institute of Technology, but almost nobody says the full name in speech; they say each letter, “M-I-T.” It is especially known for research in science, mathematics, engineering, and computer science, and people treat the name as a mark of very high technical skill. It is a school — not a company, not a government department, and not a kind of exam. Cambridge here is the city next to Boston, not Cambridge in England. Though actually, MIT’s name appears on research and inventions as much as on student life, so you will see it in news about science, not only in stories about going to college.
