Hey Ricky, I also attended the IT today. I actually got a call this afternoon advising me to come for AT tomorrow.
btw, I'm overseas applicant so that might be the reason.
How did you find the numerical test? I was only able to finish a bit more than half the paper. Previously I read that we should make suitable guesses, but I wasn't sure if that'll deduct my marks (If it's wrong). Hence I left a lot of questions blanked!
