The Council for the Indian School Certificate Examination (CISCE) is a non-governmental national level education board in India, established in 1958. It was established with the intent to replace the overseas Cambridge School Certificate Examination with an all-India examination. The board conducts three national level examinations:
- Indian Certificate of Secondary Education (ICSE) examination equivalent to class X examination.
- Indian School Certificate (ISC) examination equivalent to class XII examination.
- Certificate of Vocational Education (CVE) examination equivalent to class XII examinations.
The Indian School Certificate (ISC) examination is conducted every year after a two-year course beyond the Indian Certificate of Secondary Education (ICSE) examination or equivalent. For the two-year course students must study English compulsorily and three, four or five elective subjects. In total, thirty subjects are available in ISC. Students may select the subjects according to their chosen stream. In general, each stream has four compulsory subjects, and students also need to choose one optional subject from the available subjects in the school. Subjects get classified under four streams:
- Medical
- Non-Medical
- Commerce
- Humanities
However, the streams and subjects available may vary from school to school. Some schools may only have three streams: Science, Commerce, and Humanities. In such schools, Biology may get available as the optional subject in the Science stream with English, Maths, Physics, and Chemistry as compulsory subjects.
Besides this, students should also compulsorily participate in Socially Useful Productive Work and Community Work and must get passing grades.
Syllabus of Biology for the first year of the ISC (class XI) examination
ISC first year examination or class XI consists of two papers:

Structure of Paper I for Class XI ISC Biology
Paper I consists of two parts: Part I having 20 questions, and Part II having 17 questions. Part II further gets divided into three sections:
- Section A has seven(7) questions of 2 marks each
