Let's put it this way ~ I don't know much about the level of mathematics in China University, that is, the mathematics in the college entrance examination should be between 130- 150. For China students, this math problem is not particularly big. By the way, no one will take the postgraduate entrance examination in actuarial science, because most of them are doing research ~ Postgraduate entrance examination is ok, but it is not so useful to stay abroad ~ If the landlord returns to China for employment in the future, he'd better take a postgraduate examination. It's too difficult to teach yourself actuarial science. The landlord can buy an exam manual and try it yourself. Self-study should be difficult. Otherwise, there will be many actuaries. At present, there are only more than 4,000 actuaries in the Association of Actuaries of North America. Moreover, the landlord had better consider it well and be prepared to be an actuary. After all, only a few people succeeded in the end. I hope it helps you ~
