The BSEB 12th Science exam for 2026 follows a streamlined pattern, making it easier for students to focus their preparation. Each major science subject, Physics, Chemistry, and Biology, consists of a written (theoretical) paper carrying 70 marks and a practical exam carrying 30 marks.

For Mathematics, the entire paper is theoretical, with no practical portion, and is worth 100 marks. The objective (MCQ) section is of crucial importance: of the 70 marks for theoretical questions, 35 marks are for MCQs from practical topics.

Students are required to attempt only half of the total objective questions, which encourages careful question selection skills during the exam.
