Yeah VJTI , COEP , SP are one of the top colleges in CET
But well it depends on your rank / percentile too!
I can give you a rough idea (note that these are for the three rounds only not for the spot rounds)
For open category in CS/IT
VJTI/COEP - 100-150 rank
SP/Somaiya/DJ sanghvi - 1000-1500 rank
Note that the cutoffs drop significantly in the spot rounds
