Thank you for your informative reply Rhymie.
Some of the things I was aware of, others not. Eg I know that it's unlikely that you'll get on a course straight from school and that a foundation course doesn't act as a feeder or guarantee a place. Whether they are beneficial or not is something currently being discussed a lot on here.
I was also aware of the need for physical fitness, as it's something the principal at DD's drama school has mentioned previously.
I wasn't aware that the schools were different in training methods. However that gives me something to point out to DD about what is currently a big moan of hers. She has several different teachers with her drama group and her Secondary school and for her last Lamda exam, she had her regular teacher for most classes, then the piece was overseen by the Principal and also by a Casting Director who comes into her drama school to run occasional workshops. DD grumbled that they were all telling her different things. I shall tell her it's invaluable experience.
Thanks for the tip about reading drama school audition blogs. Hadn't thought of that. Have started looking and thought I'd found an answer to your question, as someone mentioned they got through to the last round and was one of 125 auditioning at Rada, then I re-read your thread title and realised I'd got the wrong place! Hopefully someone will know for you.
