2nd Year (Class 12) Chemistry students under the Punjab boards now have the official 2025 pairing scheme for their board exams. It covers BISE Lahore, Rawalpindi, Faisalabad, Sargodha, Gujranwala, Sahiwal, Multan, Bahawalpur, and Dera Ghazi Khan, along with the Azad Kashmir board, and lays out how the 85-mark theory paper is divided across all 16 chapters.
Second-year Chemistry mixes organic, physical and inorganic chapters, so it helps to know exactly where the marks sit before you start revising. This scheme shows the MCQ split, how short questions are grouped in Q.2, Q.3 and Q.4, and which chapters pair up in the five long questions — so you can plan your study order with confidence.

Important Things to Know
- The three short-question sections have different rules: Q.2 and Q.3 offer 12 questions each (attempt 8), while Q.4 offers 9 (attempt 6).
- Long questions are drawn from ten chapters across five questions — you attempt any three, so keep your preparation broad.
- MCQs are spread thinly across all 16 chapters, so skipping any chapter risks losing easy objective marks.
- The 2025 paper follows the SLO-based pattern, so it differs a little from older papers; even so, roughly 90% of this scheme is expected to hold.
- This scheme is built around Punjab boards. Prepare all chapters fully rather than relying on the scheme alone.
