Well at least you're all going to have a crack at it and not be weeded out because they don't like the size of your font whatever-just to cut down the potentials. So there IS a positive there. You're all on an even playing field and get to show who you are, what you can offer etc in the group activities. Treat it like a potential interview, have things ready to say/do, wear something formal etc. Don't try too hard 'to make an impression' among all the others-sometimes the quiet one may attract better favourable attention than the one who's constantly trying to impress 'ME, ME, look at ME how wonderful/marvellouss etc. I am', which may just irritate. Best of luck anyway.
