ISC Class 12 Biology Syllabus

Introduction to ISC Class 12 Biology Syllabus

The CISCE Board conducts the Examination for ISC Class 12 every year in the months of February-March. Only students enrolled in CISCE-affiliated schools are eligible to take this Examination. Another stipulation is that students can only take the Examination for the subjects they choose in 11th grade. 

CISCE holds the Examination for three separate streams: 

  • Science
  • Commerce
  • Arts.

In any student’s life, the 12th grade represents a watershed moment. Their marks in Class 12 help them secure admission to some of India’s most prestigious schools. On the other hand, Biology students usually intend to pursue a career in medicine in the future. As a result, a solid understanding of the Biology topic is required.
