10th Class Biological Science S.A.-1 (EM) C.C.E Model Paper

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.

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.

Summative Assessment Pattern

Type of questions Number of Questions Marks for each question Total marks
Essay type questions 4 4 16
Short answer questions 6 2 12
Very short answer questions 7 1 7
Objective type questions 10 ½ 5

Formative Assessment

20% of marks for the internals are allocated to
formative assessment. The areas and marks for the formative assessment
are given here under.

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

    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
