CBSE 12th

Hello,
Yes, it is helpful because unfortunately B.Com and BA syllabus tally with GS papers apart from the optional subject. So, if you take economics, it is really helpful in the exam, but you have to study very carefully and with clear understanding.
All the best.

You should go for CAT examination because IIMs require CAT score for admissions.

If you want to get a job in the banking sector, etc., then you can go for it.

No. you cannot. This is because courses available at Shanti Business School are PGDM and PGDM-C. Both are postgraduate Diploma and the minimum level of qualification required to pursue PG is graduation.
You can complete your graduation from any other institute and for PGDM, you can come to SBS.

No, you can't appear in lateral entry exam. It is basically for Diploma holders only.

Yes, after 12th with PCB, you can do B.Sc (Bachelor of Science) in biology also.

Hello Deepak,
Your cut-off marks should be higher to get a seat as the admission is not based on the overall scores. If you have a cut-off of 190 and above, then you can get a seat.

Yes, you can get admission. Minimum 60% marks is the eligibility criteria of Amity to take admission in their various courses.
You have to meet their eligibility criteria.

Yes, you can. It all comes down to how much you love the course. If you want to go for animation please do. Arena animation is one of the best institutes that you can opt for.

If you like computers you can learn computers. So, you can also consider BCA as an option. If you want to go into pure science, you can consider B.Sc. As an option, no career option is good or bad. It's you who defines it, if you work hard in any specialisation, you can achieve heights. You could only imagine.
All the best.
