yes i got pi/4 aswell for it
the last smh was "how long does it take to return to 0"
gave it a minute to sink..still didnt c so i moved on..
i used the last 5 mins i had spare to look @ it..tried couple of things but didnt get it...bah =(
imho was pretty decent/easy....i mean compare it to last 2-3 yrs cssa trials and its really nothing..
didnt get that sphere question out though...and the last smh question..the rest was good..
just hope that the 4unit trials are this easy =)
