Hi, I am genius with exceptional intellectual ability
Hello, good to meet you.  How do you know you are a genius?
Because the presence of scholars in many subjects have verified this fact.
Which scholars?  Which subjects?  I'm interested in learing how to become a genius as well.
 There is no scientifically precise definition of genius, so your best bet is talk to scholars at universities.
Do I focus on content rich subjects like sciene and history, or more abstract subjects like literature and philosphy?
I would say science it is used to indicate the presence of a particularly powerful genius mind.
