This depends on the major, but also on whether it is Mphil or PhD. If it is engineering (EE, EIE or CSE), the number of words is generally about 2 ~ 3 w, or even less (there are many charts in the experiment, and more than 1w has graduated). Management, such as real estate engineering management (BRE), generally has a large number of words, usually around 4~6w. I'm not familiar with economics, I don't know, but it's necessary to estimate the number of words.
