PECTAA has reduced the Chemistry Class 11 (FSc Part 1) syllabus for the 2027 board exams under its Smart Syllabus, also called the Accelerated Learning Programme (ALP). Below is every topic and exercise item removed from each unit of the new Chemistry-11 textbook, followed by the 2027 paper pattern. Page numbers refer to the current PECTAA Chemistry-11 book.
Quick summary
- Units 15 (Basic Separation Techniques) and 16 (Lab Safety and Practical Skills) are removed completely.
- Units 1 to 14 stay, but each loses some topics and exercise items (MCQs, short answers, descriptive questions and numericals).
- The written paper is 85 marks, 3 hours, set only from units 1 to 14.

How to use this for preparation
- Skip units 15 and 16 completely, and mark the deleted topics in units 1 to 14.
- Units 1, 6 and 10 give two MCQs each. Units 1, 3, 6, 10 and 13 give three short questions each.
- Units 1, 4, 6 and 10 have no long question, so prepare them for MCQs and short questions. Every other unit has a long-question part.
- Practise past papers, but skip any question that comes from a deleted topic.
