The admission in IIMs to PGP programs are based on CAT percentile followed by WAT, GD, PI and work experience. The initial shortlisting of candidates is done on the basis of CAT percentile and this is above 80 percentile for all IIMs for general category. IIMs requires a Bachelor degree in any discipline with minimum 50% of aggregate marks from a recognized university under 10+2+3 or 10+2+4 stream. Hence, what is the need of doing BBA MS 5 years of programme and NPAT entrance? Because when you are appearing in BBA final semester of exam, than you are eligible for appear in CAT.

According to students who have appeared in PESSAT in previous years, it is not extraordinarily difficult to crack it. Preparation can be done alongside other national level entrance exams. For example, if you are preparing for JEE Main, then it's preparation will be sufficient for PES University entrance exam also. In addition, there is an English section also, so just focus on preparing that in addition.

You need to get 99.99 percentile to get into IIM-A work on your entrance exam to score above 98 percentile.

I would prefer you MBA after your B.Com, which a wider scope and has various specialization. They offer specialization like HR, Marketing, Finance, IT, Operations etc. You can select based on your career interest.
