Dear student,

In counseling process you are supposed to lock as many choices available to you.
Now in counseling you have to select you preferred colleges and your preferred branch.
You can select as many branches available in a particular college, but you must have to keep an eye on your number of maximum choices filled.
So use your choices well.
You can select more than one branch in a single college. Also it is advisable to lock as many choices as you can so that you chances of getting a seat will be increased. You can also select all the branches of different colleges as per the number of choices available.
And it is advisable that your preference order must be from top colleges ( top branches to lower branches) to low colleges (top branches to lower branches ).
