Hello aspirant,

You have to pay the fee within the time limit other wise you didn't get allotment in second phase of allotments and also your current college will also lose, so I advise you to pay the fee immediately.

after that you can go for second phase of allotment in that you will get your higher option and on further allotments you will get your most higher option but this will depend on your score and chance of getting in that college for the applied course. If you lock the college or temporarily join the college then your option will remains but if do not take temporary admission the that option get cancelled and you will get your higher options. If you didn't get an allotments no need to pay the fee and there will be no fee memo in your home page, wait for the second phase and then for 3rd , spot and mop up.

Hope it helps!
