sorry but:
the reason of 有些地方不是很细致 is not because 第一次做这种事情, but since you did it through 中介, did not think anything about your own career plan, and thus don't realize what the difference in major means.
till now, I cannot figure out which program are you exactly in (for the IC) one.
给大家添麻烦了 <--- yes your are, what the meaning having a post that require all other to read down and down all the way?
and without saying the plan after graduation (like study / work , and perferred location)?
economics, finance, IT Management are quite different field..........and they lead to some different things......
at the end, i know you are just finding support, but not opinion for your decision.
