An 80 percentile in TANCET is a commendable score, but securing a seat in the top MBA colleges in Tamil Nadu might be challenging.

The competition for top MBA programs is intense, and these colleges typically have high cutoffs. However, it's not impossible. Factors such as category (general, reserved), specialization preference, and overall profile can influence admission chances.

To maximize possibilities, your brother should:

• Prioritize colleges: Focus on colleges with slightly lower cutoffs for his desired specialization.
• Explore other options: Consider good private MBA colleges or colleges in other cities.
• Prepare for GD/PI: Strong performance in these rounds can compensate for a slightly lower percentile.
• Highlight work experience: If any, it can significantly boost the profile.

Ultimately, the chances of getting into a top college depend on various factors. A thorough analysis of previous year cutoffs and targeted preparation can increase his prospects.

hope this helps you!!
