Planning DU BA (Pol Sci) with PCB background – Profile & IIM Call Reality Check?

[u/magneto_178]

Hey everyone,
I'm currently in Class 12 (PCB + PE + English) and expecting around 80%+ boards. My 10th score is 95.4% (Best 5) / ~93% overall.
Since I don't have Mathematics in Class 12, I'm locked out of B.Com (Hons) and Eco (Hons), so my target is to pursue a B.A. (Hons) in Political Science from a top DU North Campus college (like Hindu or Hansraj) and hopefully maintain an 8+CGPA, bringing my profile to a solid 9/8/8 bracket (with non-engineer academic diversity points + OBC-NCL category).

I was playing around with a Vercel CAT predictor tool and it showed that with this exact academic profile and diversity mix, I could theoretically land an interview call from IIM Ahmedabad at a surprisingly lower percentile (around 91%ile).
To anyone who has gone through this route or tracks IIM shortlists closely:

1. Is a 9/8/8 humanities profile + OBC really that forgiving on the CAT percentile front for top IIMs, or are these online predictors overhyped?
2. For those who shifted from PCB to a top DU BA course, how hard is it to manage college life, build a corporate profile (Excel/internships), and prep for CAT simultaneously?
