I managed to find the room at building BA2. But to do so, my
friends and I had to come 30 minutes early to do ground
recce.
Seriously, what were those admin morons thinking when they gave the
room number but not the building number? So I suppose I should ask
a guy to come to unit no. #30-256 at Choa Chu Kang St 99 without
telling him which block it is in... 
I know Biz-Ad is not very big, but it's not very small either,
no?
And even finding which room I had to go to was difficulty in
itself. I looked through the IVLE, Biz-Ad, and Engin websites (it's
a core module for Mech Engin people) before finding the room info
in some obscure corner of CORS.
Seriously, the admin needs a good kick up their Michael Ballacks.

Pardon my ranting... I'm paying the ever-increasing tuition fees
all by myself, and I demand that it be justified in every way
possible.
