For students opting for the medical stream, PCB (Physics, Chemistry, Biology) forms the core of the BSEB Class 12 Science curriculum.
While the syllabus and format for Physics and Chemistry remain identical to what was detailed previously (both featuring 70 marks for theory and 30 marks for practicals), adding Biology shifts the focus toward diagrams, definitions, and conceptual clarity.
Both Physics and Chemistry follow the 70 + 30 layout. Biology shares this exact pattern, meaning all three core subjects in PCB have practical exams.
💡 The 50% MCQ Rule Applies: Just like the rest of the science stream, your Biology paper will give you 70 MCQs on the OMR sheet, and you only need to attempt any 35 of them.
