Why Is CBSE Percentage Important for College Admissions?

Your CBSE percentage plays a vital role in determining your eligibility for college admissions in India.

Many universities and entrance exams use board percentages as qualifying criteria or tie-breaking metrics.

Here’s why maintaining a good CBSE percentage is important:

✅ Colleges like Delhi University and Mumbai University calculate merit lists using Class 12th percentages.
✅ Some competitive exams (like CUET, JEE, NEET) have minimum percentage criteria.
✅ Scholarship eligibility often requires 80% or more in board exams.
✅ It reflects consistency and academic performance in your academic career.

For example, if a student scores 95% in Class 12 and applies for B.Com at DU, they stand a higher chance of securing a seat in top colleges like SRCC or Hindu College.

So, scoring a high percentage in CBSE exams not only opens doors to the best colleges but also helps with future placements and postgraduate studies.

🎯 Tip: Aim for at least 85–90% if you're planning to apply for top universities or government scholarships.
