ICSE Class 10 Semester 1 2021 Post Paper Analysis- Biology (15th December)

The Class 10 board exams for the Indian Certificate of Secondary Education, popularly known as ICSE, have continued since 29th November 2021. Today, on 15th December 2021, ICSE Class 10 students had their last major board paper of Biology (Science Paper III), which is relatively easy to crack among all the scientific papers. Unlike previous years, after considering all parameters, CISCE was examined for 2021-22 in a semester wise pattern. 

The students did not get many gaps to study for this paper as the Chemistry paper was scheduled just on Monday. However, did this matter much to the students? The paper seemed to be of moderate to easy difficulty for the students. Let us analyse the ICSE Class 10 Biology Semester 1 Paper for 2021 and find out the details.

Question Paper Structure 

The exam was of 40 marks, and the time allotted for the examination was 60 minutes, including reading time. All questions were compulsory. For this academic year 2021-22, ICSE followed a reduced syllabus released on its official website. The syllabus was bifurcated separately for Semester I and Semester II. 

The Semester I question paper comprised of MCQ type questions that were asked from the units of Basic Biology and Plant Physiology and resembled the specimen paper shared by CISCE.  

All questions were objective MCQ type and were compulsory. There were a total of 8 main questions in the paper. Every main question comprised five sub-questions, and each sub-question was worth one mark. 

Questions 1, 2 and 3 were direct in MCQ format with question types of name the following, fill in the blanks and multiple-choice questions, respectively.

Questions 4, 5 and 6 were descriptive types in MCQ format, with question types explaining the terms, mentioning the location, and stating the functions.

Questions 7 and 8 were experimental and diagram based again in MCQ format. 

The entire paper had four options given for every sub-question, from which the students must choose the correct option and write it as the answer.

Graphical Analysis of Chapter-wise Marks Distribution (2021)

The chapter Transpiration had the maximum weightage of 10 marks, followed by the two chapters Cell Cycle, Cell Division, Structure of Chromosomes and Photosynthesis, each carrying nine marks. The chapters on Genetics and Absorption by Roots were the least weighed chapters, accounting for six marks.

Questions 1, 2 and 3 were straightforward and were purely remembering based. Most questions are from the exercises at the end of every chapter. These would not have been too hard for students well-versed with the topics covered in their ICSE textbooks. 

Questions 4, 5 and 6 were of moderate descriptive types based on the understanding abilities of students. 

Questions 7 and 8 were the basis experimental aspects of chapters on Photosynthesis and Transpiration. They were diagram based questions and would have been easy to answer if students knew the science behind these experiments. 


It would be fair to conclude that this paper was moderate to easy difficulty level with direct definitions from the syllabus. It was a great scoring opportunity for students who were regular with their concepts and had practised with sample papers.

Today’s Biology paper was the last major board paper for ICSE Class 10 students. It is time to be stress-free and relax after months of rigorous effort and dedication. Students can now enjoy their Christmas vacations and get set for Semester II exams in the New Year 2022.
