How Siddharth Institute of Engineering & Technology (Autonomous), Puttur converts percentage to CGPA

VERIFIED 2026-08-15 from the institute's own R20 regulations, read in full; formula stated at §12 with a worked example. || ⚠️⚠️ SEVERE NAME COLLISION IN THE SAME TOWN. PUTTUR HAS TWO SIMILARLY-NAMED AUTONOMOUS JNTUA COLLEGES: || • THIS ONE — SIDDHARTH Institute of Engineering & Technology (SIETK), established 19 July 2001, domain sietk.org || • SIDDARTHA Institute of Science and Technology (SISTK), established 2008, a DIFFERENT institution, also described by careers360 as autonomous and JNTUA-affiliated, also at Puttur || The names differ by one letter and one word. DISTINGUISH BY ABBREVIATION (SIETK vs SISTK), FOUNDING YEAR (2001 vs 2008) AND DOMAIN. Both will need separate registry rows. || ⚠️ AND A THIRD AND FOURTH COLLISION ACROSS THE STATE: SEAT (Siddartha Educational Academy, Tirupati, the preceding row) and PVPSIT / VRSEC (the Siddhartha Academy colleges at Vijayawada, under JNTUK, with a large multi-institution group including medical, dental, pharmacy and nursing colleges). 'SIDDHARTHA' IS ONE OF THE MOST OVERLOADED NAMES IN ANDHRA PRADESH HIGHER EDUCATION. Five distinct institutions in this registry now share it. || ⚠️ CAREERS360 CONTAINS A FACTUAL ERROR ON THIS COLLEGE: it states SIETK 'is affiliated to the Jawaharlal Nehru Technological University, HYDERABAD'. IT IS NOT — the regulation's own definitions section states 'University: Means the Jawaharlal Nehru Technological University Anantapur, Ananthapuramu'. JNTUH is a different state's university (Telangana). Careers360 also files the college under two separate URL slugs, 'siddharth-...' and 'siddhartha-...', with slightly different content. || ⚠️ THIS ROW OBLIGES ME TO WALK BACK A CONCLUSION I DREW EARLIER IN THIS SWEEP. At the JNTUA R19 row I found two copies disagreeing on the Pass Class floor — 4.5 versus 5.0 — and argued that 5.0 must be correct because the minimum passing grade (E = 5 points) makes a 4.5 CGPA unreachable for a student who passes everything, rendering a 4.5 floor meaningless. SIETK'S R20 IS A CLEAN, TEXT-NATIVE, INDEPENDENTLY DRAFTED DOCUMENT AND IT STATES PASS CLASS 4.5–<5.5 WITH THE SAME E = 5 MINIMUM GRADE. The 4.5 floor is therefore a GENUINE REGIONAL DRAFTING CONVENTION — vestigial and arithmetically unreachable, but real and deliberately written. MY INTERNAL-CONSISTENCY ARGUMENT WAS TOO CONFIDENT: it correctly identified that 4.5 is unreachable, but wrongly concluded that a document therefore would not say it. THE kvsrit AND gitamw ENTRIES SHOULD NOT HAVE BEEN AMENDED ON THAT REASONING ALONE; the JNTUA R19 discrepancy remains genuinely unresolved and needs a third copy. THE PROPOSED BUILD GUARD 'passFloor >= minPassGradePoint' WOULD FIRE FALSELY ON SIETK AND MUST NOT BE ADDED as a hard fail — make it a warning at most. || ESTABLISHED 19 JULY 2001. AUTONOMOUS, CONFERRED BY UGC — the regulation's foreword states 'Siddharth Institute of Engineering & Technology, Puttur... is an autonomous institution conferred by University Grants Commission (UGC), New Delhi'. Principal Dr. K. Chandrasekhar Reddy. || ⚠️ NAAC GRADE DISCREPANCY: the R20 cover page says 'Accredited by NAAC with A Grade'; collegedekho and agnirva both say 'A+', with agnirva giving validity to 20 June 2027. The R20 predates the current cycle, so A+ is likely current and the regulation cover stale. NBA accredited for Civil, EEE, Mechanical, ECE and CSE. || TWELVE B.TECH BRANCHES with branch codes: Civil 01, EEE 02, Mechanical 03, ECE 04, CSE 05, CS&IT 06, AGRICULTURAL ENGINEERING 07, CSE-AI&ML 09, CSE-IoT & Cyber Security including Blockchain 10, CSE-AI&DS 11, CSE-Cloud Computing 12, CSE-AI 14. ⚠️ AGRICULTURAL ENGINEERING IS UNUSUAL IN THIS REGISTRY — very few AP engineering colleges offer it. Plus M.Tech, MBA, MCA and diplomas. || DISTINCTIVE PROVISIONS: a GAP YEAR under a 'Student Entrepreneur in Residence' concept, one year extendable to two, not counted against the maximum graduation period — the most generous entrepreneurship provision seen in this batch; VIRTUAL LABS given their own regulation section; MOOCs mandatory from II year I semester with the Provisional Certificate and Consolidated Grade Sheet WITHHELD until proof of completion is submitted; five skill-oriented courses with an option to substitute industry or APSSDC certificate courses, in which case ATTENDANCE FOR THAT COURSE IS DEEMED SATISFIED. Honors gated at SGPA 8.0, Minor at 7.5, both requiring 20 additional credits; either, not both. || LOCATION: Siddharth Nagar, Narayanavanam Road, near the Tirupati-Chennai highway, Puttur 517583. Careers360 places it 'in the beautiful hill range of the Eastern Ghats'.

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 — Siddharth Institute of Engineering & Technology, Puttur (Autonomous), Academic Regulations R20, §12 Award of Class: 'Equivalent conversion of percentage of marks = (CGPA – 0.5) * 10. For example, student got CGPA = 7.31, he/she secures equivalent of percentage of marks = (7.31-0.5)*10 = 68.1%'

Applies to B.Tech (Regular) admitted from AY 2020-21 and B.Tech (Lateral Entry) from AY 2021-22, under R20. || ⚠️ CREDIT REQUIREMENT CHANGED MID-REGULATION: 160 credits for students admitted 2020-21, 163 credits for 2021-22 onwards (lateral entry 121 then 124). The regulation carries this as a footnote throughout — '* Applicable for the students joined in 2021-22 academic year and onwards'. UNLIKE RGMCET, ALL CREDITS COUNT: §9.5 states 'Marks obtained in all 160/163 credits shall be considered for the calculation of aggregate percentage of marks obtained.' || The regulation supplies a WORKED EXAMPLE, which is rare and useful: CGPA 7.31 → 68.1%. Quotable directly to an employer. || GRADE SCALE: S (Outstanding) = 10 (≥90), A (Excellent) = 9 (80-89), B (Very Good) = 8 (70-79), C (Good) = 7 (60-69), D (FAIR) = 6 (50-59), E (SATISFACTORY) = 5 (40-49), F = 0 (<40), Ab = 0. ⚠️ NOTE D IS LABELLED 'FAIR' AND E 'SATISFACTORY' — the same unusual labelling as NBKRIST, where most colleges use 'Average' and 'Pass'. || Class is awarded on CGPA (§12): First Class with Distinction ≥ 7.5; First Class 6.5–<7.5; Second Class 5.5–<6.5; Pass Class 4.5–<5.5. || Evaluation is 40 internal + 60 external. Mid-term tests are 1 hour 50 minutes — 90 minutes descriptive plus 20 minutes objective — weighted 0.8 to the better and 0.2 to the other, with fractions rounded UP. Attendance requires 50% in each subject and 75% aggregate. Two mandatory summer internships: 2 weeks after second year, 4 weeks after third year.
