Regarding Stage 2, try not to worry too much, I did not get cubes one bit, and i'm not even exagerating. There is no point analysing how many you answered etc, as we don't know how they mark it all.
Ive been waiting for my Stage 3 results for 2 weeks now, so try not to worry about it, you do sort of forget about it after about a week or so. Ive stopped waiting by the phone and checking my emails every second, it's now every hour, lol.
Good Luck! xx
