Hi,

For admission in Punjab University in B.Sc hons. courses, you need to have the following percentage: (i) 25% in the qualifying exam and, (ii) 75% in the entrance exam. This is as per the 2019 admission pattern. In previous year cut off we saw the required percentage was 10%-15% of the total marks.  You need to calculate according to the new pattern and check. 

Hope this helps, good luck!
