10th Class Biology New Syllabus and Question Paper Analysis

Biology Biology not only provides students the knowledge about life and living organisms, but also is the most scoring subject in Science stream. The study of Biology brings about an awareness of the rich diversity of life forms that inhabit the Planet Earth. It helps students to know and appreciate the precision and complexity of living processes. An understanding of the principles of Biology can help students to deal more effectively with a wide range of routine concerns such as nutrition, dieting, health care, proper use of medicines and care of domestic animals and plants.

New Biology textbook has been introduced from this academic year i.e. 2014-15. Examination question paper will be in accordance with Continuous Comprehensive Evaluation (CCE) model. Most of the topics in new syllabus are continuation of topics given in 9th standard. Heredity is the only fresh topic in new syllabus.

New syllabus consists of the following chapters.
  1. Nutrition
  2. Respiration - The Energy Releasing System
  3. Transportation - The Circulatory System
  4. Excretion - The Wastage Disposing System
  5. Control and Coordination
  6. Reproduction – The Generating System
  7. Coordination in Life Processes
  8. Heredity – From Parent to Progeny
  9. Our Environment
The concepts in the new syllabus are in elaborated form. So it is better to study the lesson before going to class. Students must be ready to discuss on questions and topics given in related headings like “Do you know”, “Think and discuss”, “Improve your learning”, “What we have learnt”.
The students those who want to get full marks must go through the entire book, irrespective of important topics. One should identify his/her weaknesses by analyzing the performance in school level exams.

Questions – Weightage
Blue print of question paper will be developed reflecting weightage to the nature of questions (i.e. very short answer, short answer, essay etc) and academic standards. No specific weightage is given to the lessons / units. Questions may be given from any lesson / any part of the textbook in a jumbled manner.
During the preparation of question papers, the weightage tables must be kept in view. Types of question are - essay, short answer, very short answer and objective; and questions will also be divided based on academic standards (how many marks and how many questions shall be allocated to each academic standard etc.).

How to get Ready for Exams
Choice will not be given for 2 mark, 1 mark and objective type questions. Only internal choice is available for 4 mark questions. Therefore every chapter must be learned completely.

Exam Pattern
Biology subject will have 50 marks; and the examination duration is 2.30 hours in addition to 15 minutes for reading the question paper.
The 50 marks paper is the combination of summative assessment and formative assessment.

Summative Assessment
  • Three summative tests must be conducted in each academic year for Class X. Public examination is conducted by the Board of Secondary Education in place of third Summative Assessment.
  • First and second Summative Assessments shall be conducted by schools themselves by preparing question papers for 80% of marks. This ensures that the children are trained to write public exams.

Sl. No.

Item for Formative Assessment




Biology – Doing the experiments and writing in the record.



A child’s written work in their notebooks – Self expression / writing to the questions/ tasks given in the exercise part under each unit / lesson. The children shall not copy the answers from guides / study materials etc. but they should think and write on their own. (These are basically class room note books)



Project works



Slip test





  • A separate notebook for the formative assessment pertaining to three items of serial numbers 1, 3 and 4 of the above table shall be maintained by each student. Serial number 2 talks about running notes taking in classroom. Students must maintain separate notebooks for taking running notes in the classroom.
  • These notebooks reflecting children works must be preserved which will be the basis for awarding marks by the teacher and for the verification of officials whenever required. The average of four FAs will be accounted for 20% of marks in public examinations under each subject
Pass Marks and Minimum Marks for Passing
  • 35% is the pass marks for all the language and non language subjects. Students must qualify in external exam (SA).
  • In non-language subjects, the students need not pass in each of the two papers separately.
  • Student must score a minimum of 35% of marks in each subject (aggregate of Paper 1 and Paper 2). Students must secure 28 marks in external public exam.
The marks based grading for Class X with the range is given here under.

Examinations will be conducted in new pattern from this academic year (2014-15). So far the students have examined previous exam papers to recognize and practice important problems. It is not possible any more with new syllabus and new exam pattern. The topics in new textbook have similarity with CBSE syllabus. So, previous exam papers of CBSE can be collected to get an idea as to what kind of questions can be asked.
