How A.M. Reddy Memorial College of Engineering and Technology (Autonomous), Narasaraopet converts percentage to CGPA

VERIFIED 2026-08-15 from the college's own AMR-24 regulations; formula stated verbatim in §19 immediately below the Award of Class table. || INTERNAL CONSISTENCY PASSES: (CGPA − 0.5) × 10 reduces to 10·GP − 5, mapping grade points onto mark-band midpoints (GP 10 → 95 against a ≥90 band; GP 9 → 85 against 84.5; GP 5 → 45 against 44.5). || THIRD COLLEGE IN THIS BATCH WITH IDENTICAL CLAUSE WORDING — SRKR R23 §22, AEC AR23 §16 and AMR-24 §19 all carry the sentence 'CGPA to Percentage conversion Formula – (CGPA – 0.5) x 10' with identical class bands and an identical S/A/B/C/D/E grade table. A common drafting template is clearly circulating among JNTUK-affiliated autonomous colleges in coastal AP. Corroboration only — GVPCE and GVPCEW proved shared drafting does not guarantee a shared constant, so each college still needs its own read. || DUAL-REGIME COLLEGE, CLEANLY EVIDENCED: the site runs parallel Exam Cell sections for Autonomous and JNTU-K, publishes both institute and university academic calendars, and issued both AMR24 and JNTUK notifications in the same period. Results pages confirm live AMR24 examinations (I-B.Tech I and II Semester AMR24 supplementary, January 2026). This is the clearest cohort boundary encountered so far in the batch and should be modelled explicitly rather than smoothed over. || THE STRUCTURAL PRE-FILTER HELD: this college's navigation contains an explicit 'Regulations & Syllabus' link under Exam Cell → Autonomous, and the regulation was found immediately. Every college in this batch with such a link resolved; every one without it (LBCE, SVPEC, ASIST) came back NOTFOUND. || AMR-24 retains boilerplate references to 'the University' and 'the Vice-Chancellor' throughout (e.g. §27(iv)), inherited from the JNTUK template it was adapted from. This is drafting residue, not evidence that JNTUK sets the conversion — the document is the college's own autonomous regulation.

Worked example

Take a percentage of 75%. Reversing the official A.M. Reddy Memorial College of Engineering and Technology (Autonomous), Narasaraopet formula % = (CGPA − 0.5) × 10 gives a CGPA of about 8.0. Change the percentage above and the CGPA updates instantly.

Which figure is authoritative?

A percentage printed on your transcript is the official figure. This reverses the college's own conversion, so the CGPA shown is an estimate — useful for checking a number, not for quoting as an official grade.

Source & verification

own — A.M. Reddy Memorial College of Engineering and Technology (Autonomous), Academic Regulations AMR-24 for B.Tech (Regular-Full time), §19 Grading / Award of Class: 'CGPA to Percentage conversion Formula – (CGPA – 0.5) x 10'

Applies to: B.Tech (Regular) admitted from AY 2024-25 onward and B.Tech (Lateral Entry) from AY 2025-26 onward, under AMR-24. Grade scale: S = 10 (≥90), A = 9 (80-89), B = 8 (70-79), C = 7 (60-69), D = 6 (50-59), E = 5 (40-49), F = 0, Ab = 0. Class is awarded on CGPA, not percentage: First Class with Distinction ≥ 7.5, First Class ≥ 6.5 and < 7.5, Second Class ≥ 5.5 and < 6.5, Pass Class ≥ 5.0 and < 5.5. Non-credit audit courses are graded Satisfactory/Unsatisfactory and excluded from SGPA/CGPA; no class or division is awarded for the Honors programme. COHORT SPLIT — IMPORTANT: AMR-24 covers only students admitted from 2024-25. Students admitted BEFORE that follow JNTU Kakinada regulations R16, R19 or R20, where the conversion is (CGPA − 0.75) × 10, NOT this formula. The college's own circulars confirm this — it published separate 'R20-IV-I B.Tech', 'R19-IV-I B.Tech' and 'R16-IV-I B.Tech' examination timetables in December 2024, and maintains a distinct JNTU-K section in its Exam Cell alongside the Autonomous section. Check the regulation code on your hall ticket: AMR24 means this formula; R16/R19/R20 means JNTUK's (CGPA − 0.75) × 10. Using the wrong one shifts the result by 2.5 points. NOT TO BE CONFUSED WITH Narasaraopeta Engineering College (NEC/NRTEC, nrtec.in), a separate autonomous college in the same town with a different formula.
