    How essential is it to know QFT and/or GR before learning string theory?

    Is QFT more important or both equally as important?

    Well given that string theory uses language from both areas, I'd say it was very important to have a working knowledge of GR and QFT before trying to learn that mathematics of string theory.

    QFT for certain, GR is useful.
