Hey Adharsh! You Don't need to do it separately.if you have good marks you will get the college through tancet. You have to apply for the counselling in the PSGIM.you have to send your application to the college,they will publish a list of cutoff and ranks (Common merit list) , and then you will easily get to know if you are getting admission or not,on the basis of your tancet marks. Hope this may help you.
