Hello Aspirant,
The vacancy of each branch is different and also different for each category. Each year depending upon how many candidates have applied for spot round, the seats are filled and are left vacant. If during the councelling process seats are left unfilled , then fir filling those unfilled seats, the spot round is conducted. Students are given preference for the spot round according to their merit and rank details.
So, for NIT Andhra Pradesh, each year's spot round vacancy list is different. It is not necessary that if last year the vacancy seats were more then this year also seats will be more. Depending upon candidates who have applied, seats could also be less.
Usually the colleges don't upload spot round vacancy list all year round. So you can check if the list is still available on their official website. Because, some colleges delete the vacancy list status after teh spot round is conducted.
Hope that helps.
