How to Score Full Marks in CBSE Class 9 Science

A comprehensive analysis of the CBSE Class 9 Science paper to help you prepare and crack the exam

By Admin 24th Feb, 2018 11:31 am

Science plays an important role in life. While Science or General Science is still a common subject, the disciplines of Physics, Chemistry and Biology have now emerged. Encompassing these disciplines, the Science syllabus for CBSE Class 9 has been designed around seven broad themes, viz. Food; Materials; The World of the Living; How Things Work; Moving Things, People and Ideas; Natural Phenomenon and Natural Resources.

There is a belief that one cannot score full marks in Science; however, an increasing number of students have been able to score 100 in this subject. Yes! Scoring a high percentage of marks is not difficult. You just require the right study strategies and correct understanding of the concepts.

And well, you certainly don’t need to be nervous or confused, because we at TopperLearning are here to help you. You can also always go through our sample papers to get acquainted with the paper pattern.

1. CBSE Class 9 Science Exam Paper Pattern

In the new scheme of examination, CCE and the term system have been replaced with a single annual exam. The exam will be for 80 marks, and 20 marks are for internal assessment at school. CBSE has issued detailed guidelines on how the internal marks will be divided among different activities.

80 Marks

(Theory Examination)

Student has to secure
33% marks out of 80
marks in each subject

20 Marks

(Internal Assessment)

Student has to secure 33% marks out of overall 20 marks earmarked in each subject

Periodic Test
(10 Marks)

(5 Marks)

Subject Enrichment
(5 Marks)

2. CBSE Class 9 Science Weightage of Chapters 

There is less time for the exam and everyone wants good marks. But the real challenge is knowing what kind of questions will appear in the exam. Below is a blueprint.

4. Important exam Tips to note for (Theory Paper - 68 Marks):

(a) Physics

  • Revise the concepts in a sequential order. For example, only after understanding and being thorough with the concepts of Motion, one will be able to easily understand and revise the concepts of Laws of Motion. This not just boosts confidence but also develops interest and helps to save time.

  • Write down all the formulae with the full meaning of the variables and the SI and CGS units of each of them. This will help to prevent any silly mistake while solving a numerical.

  • Avoid revision by going through the concepts virtually. Practise learning and writing on your own regularly.

  • Avoid taking up any new concept just before the exams, practice and gain expertise on that which has already been learnt.

(b) Chemistry 

  • Focus on application-based questions from the ‘Matter in our Surroundings’ chapter.
  • Solve as many numericals on ‘Mole Concept’ and study the valencies of elements.
  • Practise writing chemical formulae.
  • Remember the theories on various models of the atom.

(c) Biology

  • Concentrate on all the cell organelles, and an application-based question is expected from osmosis, diffusion and plasmolysis.
  • Try to remember the similarities and dissimilarities of various phyla of the Animal Kingdom.
  • Remember the rules for writing a scientific name of an organism.
  • An inferential based question is expected from diseases in human beings.
  • Know the various modes of transmission and the symptoms of communicable diseases.
  • Biogeochemical cycles must be a compulsory inclusion while studying; all the cycles are important.
  • Remember the breeds of poultry, milch animals and fish.

5. Important exam tips to note for practical based questions (12 marks): 

  • Two questions each from Physics, Chemistry and Biology.
  • For Biology, questions will be from identification of tissues, function of the tissues, onion peel and human cheek cells experiment.
  • For Chemistry, numerical-based questions on compounds and mixtures, and molecular mass.
  • For Physics, questions will be on laws of reflection of sound, determination of density of solid and determination of speed of pulse.

6. How to Prepare for CBSE class 9 Science exam:

7. CBSE Class 9 Science Study Tips to Follow:

a) If you’re studying Science on a particular day, divide the time for at least two subjects – Physics/Chemistry, Chemistry/Biology or Physics/Biology.

b) Take chapters which are easy for you to remember and finish them on time (as suggested for preparation tips from the flowcharts).

c)For example, if you are taking the combination Biology/Chemistry or vice versa, study the ‘Our Environment’ chapter and ‘Chemical Reactions’ and note down the typology of questions. Then start studying the ‘Life Processes’ chapter and ‘Carbon and its Compounds’.

d) Follow an easy–difficult combination of studying. 

e) Important topics suggested should be studied with utmost concentration.       

f) After you study a chapter, make a habit of jotting down some important points. This will help in remembering the concept and improve handwriting.

g) Draw diagrams when you get tired of reading a concept.

h) Eat, sleep, study and relax – the ultimate way to score good marks.

i)Do not stay awake till late at night before the day of the exam.

8. CBSE Class 9 Science Exam Tips while attempting the Science Question Paper

•  Do not dry to divert yourself in any sort of situations.

•  Read the question paper first.

•  Start and continue with any one pen while starting the answer. Do not change the ink.

•  Answer questions which you know and are comfortable in answering FIRST.

•  Follow bullets/steps while answering any question.

•  Good handwriting and neatly written answers help a lot.

•  Answers should always be concise and precise, with a good introduction and conclusion.

•  For 5-mark questions, try to divide the answers in any way that you can so that it would be easy for the examiner to have a good impression.

•  Keep a watch over time while writing answers because you have to attempt 27 questions in three hours.

•  Do not spend too much time on one question.

•  Review all answers in the last 10 minutes.

•  Diagrams should be drawn with a pencil. Do not use a pen.
