I'd say.... do as the day comes .... the rank cutoffs in the cusat website don't include spot admission ... they are only 1-2-3 allotments ... so wait through to the 3 allotments ...if u don't get a seat go for spot round if the seats are left ... which is always the case ad many branches have vacant seats .... and yes if there is availability u can easily get other branches ... but do the hard work and keep ur pointer high...only then u can be upgraded...
