How do I fill choices in Jossa to get better college?

Just two simple tricks-

1. Fill the choices in order of your actual preference – so if college A with branch XY is above college B in branch YZ, that should mean you wanted A with XY more! True for every single pair of of A XY and B YZ.
2. Don’t think about cutoffs at all while filling the form, this is as crucial as step one.
