Exactly one calendar month to ATCL. Have recorded myself a few times and the main impression is "not as bad as I thought". I have a few run throughs coming up so that should shake out a lot of things.
Would you be willing to post your programme? I'm currently working towards ARSM (probably next May) and then I'll start working on DipABRSM, so diploma programmes are very much on my mind right now.
