Ha ha! What are you doing skipping classes all day? Your ideal and goal are stocks, etc. Why not skip class and apply for a job in a securities/futures/foreign exchange/investment company? See what they want from you. You don't even know the basic requirements of these jobs, and you still say that you want to engage in this industry? Are you still sleeping?

I think my words may be a little harsh. Whether you can accept them is your own business, and it is also the basis for determining whether you will become a talent and scum in the future.
