Frequently Asked Questions
Is a conversion certificate mandatory for campus placements? ▼
Not always. Many companies operating at JNTUH campuses are already aware of the CGPA system and calculate your percentage themselves. However, for companies that have a strict "60% minimum" cutoff and verify documents, the conversion certificate avoids confusion.
Can I convert CGPA 6.5 as 65% for a job with 65% cutoff? ▼
Using JNTUH's official formula: (6.5 − 0.5) × 10 = 60% — not 65%. However, some private companies accept CGPA × 10 (i.e., 65%) if you show the conversion certificate explicitly. Always clarify with the recruiter which formula they accept before applying.
Does the conversion formula differ for R22 vs R18? ▼
No — the formula (CGPA − 0.5) × 10 is the same for R22, R20, R18, R16, R15, and R13 regulations. JNTUH standardised this across all B.Tech and M.Tech programmes.
My college is not issuing the certificate. What do I do? ▼
You can write directly to JNTUH's Controller of Examinations at JNTUH, Kukatpally, Hyderabad — 500085, referencing your roll number and regulation. Alternatively, share the official JNTUH academic regulations circular with the employer directly, as many recruiters accept the published formula as sufficient proof.
