The syllabus for the K4 group in the Polytechnic exam (often associated with Mechanical Engineering) generally covers subjects like:

1. Physics

2. Chemistry

3. Mathematics

The exam usually has two sections:

General Section: This includes Physics, Chemistry, and Mathematics.

Engineering Section: Focuses on Mechanical Engineering.

The General Section typically accounts for about 40% of the exam, while the Engineering Section makes up the remaining 60%.

For a more detailed and specific syllabus, I recommend checking the official JEECUP syllabus or the relevant exam board’s website to get the most accurate and up-to-date information.
