In Toronto, Canada, accommodation and tuition add up to about 200 thousand RMB a year. If you study economics, you can go to an investment bank or be a market researcher after graduation. After graduating from mathematics, I have many directions. I can be a teacher, financial securities analyst and statistician. These two majors have a large demand and a wide range of employment, which makes it easier to find jobs. I hope I can help you and wish you success.
