1. Core Objective of the C24 Curriculum

The C24 scheme aligns polytechnic education with the National Education Policy (NEP) and National Credit Framework (NCrF), introducing modular learning, project-based laboratory assessments, and updated emerging technology electives (such as Artificial Intelligence, IoT, Cloud Computing, and EV Technology).

Continuous Internal Evaluation (CIE) carries enhanced weightage to reward consistent classroom attendance, periodic assignments, and practical skill tests.

2. Continuous Internal Evaluation (CIE) vs Semester End Exams (SEE)

In both C21 and C24 schemes, total evaluation is divided into internal assessments (CIE) conducted at the college level and board examinations (SEE) conducted centrally by SBTET.

CIE components include unit tests, assignment submissions, seminar presentations, and laboratory continuous rubrics. Maintaining high CIE scores is vital because internal marks directly cushion semester grade point calculations.

3. Credit Structure & Minimum Passing Standards

Theory subjects typically carry 3 to 4 credits, while practical laboratory courses carry 1.5 to 2 credits.

Students must secure minimum passing marks in both internal assessments and semester-end examinations independently to be declared passed in a subject code.
