BCA

Nope, YCMOU is not the best option. It is a decent college to pursue BCA.

BCA or B.Sc (HM) both are completely different course in each and every aspect. BCA is Bachelor of computer application i.e related to computer programming, coding, languages, etc. whereas B.Sc (HM) is related to hotel management and catering technology. It depends on you that in which sector you have an interest or in which sector you want to pursue your career.
Choose wisely!
Good luck!

All the best!

MS in computer science from abroad like US, UK is better option. Actually if you compare it will be financially equivalent to pursue MBA from top institutes of India or MS from US.

Most of the universities in USA prefer students who have completed their graduation by doing 10+2+4. You are advised to do one year PG diploma in computer related subject to become eligible for MS in USA universities. You are advised to appear in GRE.

You are a BCA student. If you are interested coding, progamming, etc. then you can go for MCA. If you are interested in the management field, go for MBA (IT).

For MCA admission, the first preference is given to ranking in entrance exams i.e. PGCET or KMAT. There are some colleges offering MCA on merit basis. You can try in BITS. Else Pune or Bangalore is a good option.

Yes, admissions are open for the academic year of 2017-18.

There is nothing like I am weak. It's just our psychology. There are many students whose weak subjects become their whole career. Maths is all about practice. I think in order to test yourself you should be practicing a sum and understanding its concept and then you should try to solve a sum on your own without referring the solution if you come to be correct then maths is your subject. If not then you can opt for BCA. But be confident while solving because if you set this in your mind that I am weak in this subject you will never be able to solve any problems of maths.
