Where are NCERT solutions?
Open the NCERT-style practice link on this subject or chapter. For word-for-word textbook exercise answers, use the NCERT book itself; we do not copy solution keys from other websites.
What is the suggested URL pattern?
Hub /cbse/, then /cbse/class-11/, then subject and chapter slugs.
Why is this a separate URL?
So students searching for “Competency Based Questions” land on a filtered set, while the chapter page remains the full 100-question bank. Same facts, different search intent.

Follow this loop every day: mixed test, current affairs, then today's subject. A new set arrives tomorrow.
