Hi Aspirant,

See what happens usuaaly is the change like that is not considered as the happening of it is completely related to availability of seats and once you have opted for a part time course you may have to wait untill to take admission for you to get some sort of upgradation if it is allowed. Here is the brochure for PGCET candidates there might be something useful in it.
