A single, official PDF with weightage isn't released by NTA. However, you can find numerous resources online offering syllabus breakdowns and weightage estimations from various coaching institutes. Verify the source's credibility before relying on it.
Physics, Chemistry, and Mathematics are the three core subjects. Each subject encompasses various topics, ranging from basic concepts to more advanced ones depending on the level of difficulty.
While the core subjects remain the same, minor modifications or updates might occur each year. Always refer to the official NTA notification for the most accurate and updated syllabus.
The most reliable source is the official website of the National Testing Agency (NTA). Look for the information bulletin or syllabus document released specifically for the 2023 exam.
The official NTA doesn't explicitly provide a topic-wise weightage. Weightage is usually estimated based on previous years' question papers and analysis by experts and coaching institutes.
