Expect to work 80 hours a week to start and also realize that many investment banks are downsizing, so competition is fierce.
All of those are good subjects. However, the advice that you also take economics was good. If you can't....then you can't. But the others (except for P.E., which I'm guessing you may be required to take) are all appropriate to becoming an investment banker.
Basically, you should be taking courses in business and finance.
Hope that helps.
Even more important is to learn when to capitalize and when not to. If the writing in your resume was anything like your question I would throw it straight into the trash bin.
I'm going to do Marketing,Accounting,Business,P.E & English and i wanted to know that if i perform good and get good grades is it possible for me to become a investment banker ? I've heard that ill need economics but i didn't get the grades needed to get economics but is it possible for me to do Banking and international finance with these subjects ?
