[Q]What subject is required to learn String-Theory

[good_phy]

Hi,

I'm curious about What world it is, What happened to the initial world to become this state.

I'm student undergraduate and I got admission from plasma laser lab of graduate school.

But i want to learn about String-Theory. So i planed to learn relevant subject step by step.

But What subject i need to learn to be qualified to learn String Theory?

Shoud i learn all theory such as QED,QCD,QFT?

Is there other mathemetical subject we need to learn?

Please lead me into right direction!

Thank you for your help, World beginning explorer!
