Hello,

Yes in the first case if you get college A alloted and decide to 'float' it you will reserve a seat in college A but if a better college is alloted to u in next round your seat in college A will get cancelled as you had not 'freezed' that seat or payed seat acceptance money.

In the second case if you wont get college B yes you will get seat A provided you had not choosen the option of 'slide' or cancel in round 1.You can then opt for further rounds
