Today, on 29th March 2023, ICSE Class 10 students had their last board paper on Biology (Science Paper III), which is relatively easy to crack among all the Science papers. Every year more than a lakh candidates appear for the ICSE examination, and this year nearly 1.7 lakh students appeared for ICSE 10 examination.

This time the students got a gap of two days to study for Biology paper as their Hindi exams were scheduled on Monday, 27th March 2023. Today’s ICSE 10 Biology exam underwent without any hitches, and students felt that the paper was of moderate difficulty level, not too challenging nor too easy.

Question Paper Structure

The ICSE 10 Biology exam comprised a theory paper of two hours with questions of 80 marks and an internal assessment with practical work carrying 20 marks. We will focus on today’s theory paper.

For the academic year 2022-23, CISCE returned to its old paper pattern, which involves a combination of objective and subjective questions. So, let’s first see the question paper structure before moving on to paper analysis.

The theory paper was precisely in line with the specimen paper released by CISCE. The question paper was divided into sections: Section A (40 marks) and Section B (40 marks).

Section A had two main questions—question 1 comprised 15 MCQs, each carrying 1 mark, accounting for 15 marksQuestion 2 contained five sub-questions, each carrying 5 marks accounting for 25 marks. Section A consisted of memory-based and understanding-based questions.

Section B had six questions of SAQ type, each with 10 marks. Of these six questions, students were expected to attempt any four questions, thus accounting for a total of 40 marks.

In section B, every main question comprised five sub-questions. Of these, one sub-question carried 1 markthree sub-questions had 2 marks each, and the remaining 1 question carried 3 marks

This section included a mixed bag of questions in the form of Name the following, Complete the table, Diagram-based questions, Draw diagrams, Give reasons, etc.

Here, we decode the ICSE Class 10 Biology board paper with all its elements and discuss the chapter-wise distribution of marks.

  • The paper was moderately complex and lengthy.
  • It was well-balanced, with an equal mix of hard, easy, and direct questions.
  • The MCQs in section A were the easiest part of the paper.
  • The short answer questions were also simple and mainly consisted of explicit definitions and straightforward answers.
  • A few long-answer questions were tricky and required critical thinking but were manageable.
  • Some students faced difficulty in drawing diagrams and complained about the confusing questions.

Expert Feedback

  • Overall, it was a moderately tricky paper.
  • Section A had easy-to-moderate questions that tested the students’ basic knowledge and understanding of concepts.
  • Section B was moderate and followed the given paper pattern. It has questions on familiar topics.
  • The exam wasn’t lengthy if students followed the word limit.
  • Also, if students had spent more than half an hour in Section A, they would have certainly felt its crunch in Section B.


It would be fair to conclude that this paper was moderately complex, not too challenging nor too easy. It was well-balanced, with an equal mix of hard, easy, and direct questions. Students who studied through the specimen paper shared by the CISCE could complete the exam on time. Students who had practised solving questions and had a good understanding of the concepts would be able to score 65+ marks out of 80.

Today’s Biology paper was the last board paper for ICSE Class 10 students. It’s time to be stress-free and relax after months of rigorous effort and dedication. Students can now enjoy their summer vacations and get set for a new chapter in life after boards.
