There is no special challenge for science students in cracking CAT. In fact science students have advantage in Numerical Ability, Data Interpretation and Logical reasoning. If you have good communication skills (both verbal & non-verbal) then you can easily crack CAT. MBA opens opportunities in different management functions in different industries.

ISB&M take admission on CAT - 50,CMAT - 50, XAT- 50. Moreover we do stress more on entrance exam it totally depends upon the individual.
All the best !

IIT-Bombay, SP Jain and NMIMS are the best colleges to aim for.
IITB cutoff- 98 percentile
SP Jain - profile based calls but have 95percentile to be on the safer side.
NM takes NMAT.

It depends on the college you are going to choose. All the colleges have different criteria and some private colleges give direct admission, but CMAT is compulsory for the same.

IBS Business School and Entrepreneurship Development Institute of India are the best in Ahmadabad. They accept CMAT score.

The syllabus for MAT and bank POs are the best. You can get through both of them if you could prepare for bank POs, since PO exams will be tougher than MAT.

140 is a below par score, I would suggest you can try once more or wait for result of other entrance exams. You might get better colleges based on the results of other exams.

CAT is considered. Your HSC marks is just a part of consideration .
It won't stop you from getting admission in college.

Minimum will be 90 percentile.

You can get many books in the market. Author is not a problem, just ensure the topics asked in CET are covered.
