Maths Spl

Since you have statistics of all three years, you can apply for M.Sc. Statistics. Aggregate marks are 50% overall and 60% in statistics in your graduation.

I think you should go with B.Sc. Statistics, because B.Sc. Data Science students have big competition with B.Tech CSE students and most of the companies prefers to select the B.Tech CSE students in place of B.Sc. Students.

For doing BBA after class 12th, maths is not compulsory. Eligibility says 10+2 in any discipline. There are many colleges that offer BBA like SP Jain in the western part of India and if you are looking for Delhi NCR then colleges of DU, IP and IILM University Gurugram are the options that are available.

In most of the Flying Academies, the Physics and Maths are the mandatory requirements at class 12th level for CPL. However, other courses like Student pilot and PPL can be done on the basis of class 10th.

The eligibility criteria of GGSIPU for B.Com.(Hons) is given below:

So from above, mathematics is not necessary for B.Com (Hons) of GGSIPU.
