Hello.

Eligibility criteria for B.Sc with Maths honours includes that the student should pass any 10+2 Or equivalent examination with Mathematics as their subject. The merit list is prepared according to the aggregate obtained from best four subjects including mathematics and the examination should be by a recognised board or institute. So any of your optional subjects do not matter as long as you have passed 10+2 or equivalent exam with atleast mathematics as one of your main subjects. Hence you are eligible even if you have PE as your optional.

The 2020 cut off list had the following  " best four subjects percentage aggregate" for different streams. So you can check for yourself whether you can get into B.Sc Hons mathematics at St. Stephen's.
