Hello Akshat,
Scholastic Aptitude Test or SAT is the exam to be cleared before taking up undergraduate courses in USA. It was introduced almost 90 years back and is still surviving. COmmercial Pilot Licence or CPL is a different and one needs to join flying school to get this. But yes, for BS in US, one needs to clear SAT.

Dear Adiline!
Two things to say, #1) Maths is available in firth year in not just B.Com but also in BBA BMS etc. So it does't mean that every person after graduation becomes eligible for MCA. #2) In order to do MCA. You need to complete your graduation in BCA. Means, you need to a have the degree in PCM (12th) and Computer Application in graduation. Hence, I am afraid to say that after B.Com, you are not eligible for MCA. Hope this helps. Upvote the answer if you feel satisfied. Good Luck.

Yes, you are eligible for railways exams.

No, there is no need to clear NEET exam for B.Sc Nursing. Actually, even if you do not give this exam, you can apply in best colleges for B.Sc Nursing. Apply in DU on the basis of your 10+2 marks. Best of luck.

Universities allow a Post-Graduation in the subjects, you have studied in Graduation. To do M.Sc in Geography, you must have this subject in Graduation. However, a solution is that you can appear in additional papers of geography graduation subject and do M.Sc Geography.
