Hi Pari,

Yes, the cutoff for B.Sc. Statistics Honours is same for both commerce and science streams. The best of four should include one language, Mathematics and two core subjects from the stream you chose. If Maths is not included, a deduction of 2.5% is applied. The eligibility for the course in most colleges itself demand at least 50% in Mathematics in the class 12 exam. 

All the best!
