I wasn't originally taking drama but the drama teacher asked me to audition for Bye Bye Birdie. I did and got the lead role. Initially I was kind of scared but once I did it I got bitten by the bug and loved it.
Before I got Doctor Who I went to the Guildhall School of Music and Drama. I went back to take the final grade exam which is the grade you have to take before you can take the teacher's diploma.
