ICSE Biology Class 10 Latest Syllabus 2023-24
There will be one paper of two hours duration of 80 marks and Internal Assessment of practical work carrying 20 marks.
The paper will be divided into two sections, Section I (40 marks) and Section II (40 marks).
Section I (compulsory) will contain short answer questions on the entire syllabus.
Section II will contain six questions. Candidates will be required to answer any four of these six questions.
