Hello ,

First of all you have not mentioned about which counseling you are referring to . But in general while choosing a college you can choose as many options as you want and yes as many branch as you want in different colleges and lock your choices but remember locking choices doesn't mean you will get the college  but you will get only one college from your choice list and this will be alloted to you by the counseling authorities on the basis of your rank and order of preferred choice .

When you get a seat you will then have three option :-

• Freeze :- If you are satisfied with the seat you have got you can freeze it and you will have to report at reporting centre pay the fee and verify your document and it is over for you , you have got admission in that college .
• Float :- If you don't like the college and think that you can get some better college then you can choose this option in this you will have the seat alloted to you and go in next round for better option if you get better college then it is ok if not then the one you have got in privious round is already yours .
• Slide :- This means you accept the college but want to go for better branch in same college . So , you can opt for this , again in this if you get good branch then it is ok otherwise you already have the privious branch you have been alloted .

Hope this will help you .
