Hello student,

In Lucknow university there are near by 480 seats available for bachelors of science (B.Sc) Mathematics. 

On the other hand you there are near by 280 seats available for bachelors of science in biology (B.Sc bio).

As the seats are less and the number of applications for these seats are found to be 10 times every year. So, To grab a seat there is not that much easy.

Hope it helps. 

Thank you  :)
