Hello Annie,
You admission entirely depends on your merit number.
Their are a total of eight government bsc nursing colleges in Gujarat and the total number of intake of all the colleges is 400 according to the last year's data.

• The last rank (merit number) details of few colleges is

• College of nursing, Rajkot- 2125
• College of nursing, Sidhpur- 1419
• College of nursing, Bhavnagar- 1621
• College of nursing, Jamnagar- 1031

Whenever the merit list is released you can see these last rank details and know your chances of selection.
I hope this helps.
All the best for the future!!
