Verified vs. official syllabus Checked 2026-07-01

Subject names, credits, and semester placement are cross-confirmed against JNTUK's own centrally-administered exam records. Detailed unit topics are sourced from an autonomous JNTUK-affiliated college's published syllabus and have not been independently verified against the university's own document -- autonomous colleges may adapt unit-level content locally.
