Ipmat or CAT

i scored 86 percent in 10th and will most probably get 95 plus in 12th
im a pcm student and my parents are insisting me to pursue btech/b.s for ug
my initial plan was to do btech and then MBA from a good school because im interested in management more than techie stuff
but i just came across alot of scenarios where engg. students were less prioritized during admissions
so im trying my hand in ipmat but idts itll be possible this year because other engg exams are clashing w ipmat

should I take a partial drop and try for ipmat next year or should I do btech and then MBA

also lets say I make it to the PI round next year , will this engg thingy cast a bad imagine in front of professors?
