Hello Shammy,
If you have not applied to SRM yet, you can't get admission.

If you are taking BCA then you need to strong in the related subjects especially maths.
You have to first analyse the area where your strength lies.
Based on that choose the appropriate stream. For BCA, all institutes will expect the candidates to have studied physics, chemistry and maths.
For some of the institutes, there will also be an entrance exam.

I shall answer the second question First. what is the USE of MCA? Actually, any master degree takes younto real specialization and enhances your expertise and makes you senior in thing. MCA will certainly teach you things that have not been part of BCA. If you are doing MCA, complete the degree with good learning. While doing MCA You Must search opportunity to work as a freelance developer or designer.

Hello Aatmaj,
If you have done BCA then you must have passed your 12th almost three years back. These days almost all state govt's and IIT too have only three year window after 12th within which you need to apply. Doing Aeronautical engineering in any Institute other than IIT is of no use. So I suggest please think of doing something different.

Yes, you can apply for MBA in operations management as well as other fields of MBA if you want. Top B-Schools like IIMs, Xavier's, NMIMS, Great Lakes-Chennai, IMT, etc. accept CAT and XAT but NMIMS only accepts NMAT.

I am.of the new that Aerospace Engineering is based on the Non Medical Stream that you take in XII being the qualifying for graduation. if you want Admission in a Graduation of Aerospace them, having PCM, it's possible as per selection Criteria.
if you want to do Aerospace after BCA, that does not.seem possible.

Nothing is easy as you are doing graduation, so there is some level of education. But if you really wants to know then I think BCA is quite better for you to do.
All the best.
