“The only limit to the height of your achievements is the reach of your dreams and your willingness to work for them.”

After two years of ‘doldrums’ kind of situation due to the pandemic, students are witnessing a smooth channel of CBSE Board Exam going to be held for Session 2022-23. The dedicated, concerned Faculty and Management of Manav Rachna International Schools have decided to publish a Series: #CBSEXAMTipsTricks to help students appearing for Board Exams Session 2022-23. The idea behind these posts is to address the doubts of those appearing for CBSE Board Exams. We have tried to resolve the general doubts with some excellent tips & tricks as we believe ‘Koshish karne walon kee kabhi haar nahi hoti, Lehron se darke  nauka  paar nahi hoti’. ~ Editor



Board exams are considered an important stage in student’s academic life. This is because it’s the stage that affects the career prospects in future.

Preparing for exams can be a challenging part of a student’s life, yet performing well in these, can help in deciding which course to study going forward in their lives, so it is important that the students prepare for it well.

With CBSE Board Exams approaching soon, it’s time to sharpen the skills  of the students to manage  time effectively and put in the best efforts to attain good scores. Thus to assist the students to prepare the best for their Boards, we are providing some tips.

CBSE Class X Science Preparation: General Tips

  1. Read NCERT science books thoroughly. Do not leave any single line, diagram, table, example, question, term, or graph from the NCERT book.
  2. Maximum weightage is given to Biology section followed by Chemistry and then by Physics.
  3. The updated paper pattern contains ‘Case study-based questions’ and ‘Short answer type questions’. Give emphasis on application-based questions.
  4. Practice case study questions from important topics like Physics: Electrical circuit, Common measuring instruments, Joule’s heating effect of current, Magnetic field and field lines, Force on a moving charge in a magnetic field, Electric motor, Electromagnetic induction, Biology: Reproductive system in human beings, Monohybrid and Dihybrid cross, Food chain and Food Web, Chemistry: Bonding of carbon.
  5. Flowcharts to remember concepts in a concise manner ensuring revision in less time.
  6. Practice Solved Examples and back exercises from NCERT texts chapter-wise.
  7. In Biology and Chemistry, the labelling of diagrams/reactions should be practiced as both diagrams/reactions-based questions can be asked based on the sample paper.
  8. Another tip to prepare for CBSE Board Exam is to practice more and more sample papers and CBSE previous year question papers. The more you practice the more you will get familiar with your weak areas and strong areas. It will help you boost confidence and will curb exam-related anxiety, fear, and stress. 
  9. This is one of the best tips to cover your CBSE board exam syllabus. You do not need to have too much on your plate. Avoid taking all the easy topics in one day and the difficult ones in one. Follow a mix and match strategy instead. In your day take a combination of topics that includes both easy and difficult ones. Doing all the hard ones in a single day can make you feel frustrated. So, follow the given strategy to avoid this.
  10. Board Exams require long hours of study and such long hours of studies can make you feel bored and frustrated so a tip to prepare for CBSE Board Exam is to take a 10-15 minutes break after every hour. This will keep you fresh and help you concentrate better.
  11. Revisions are important. They help you get a strong hold on the topics and let you know your strong and weak areas. Revisions help you remember what you have studied already. The more you revise the more you will be able to champion in your syllabus.
    Tips for Physics

    • Practising the numerical questions and revising the concepts is the key to achieving good scores in Physics.
    • Key words are very important in one-word questions/ definition-based question.
    • In 2-3 marks numerical problems

    Formula with substitution carry marks

    Step wise distribution carry marks.

    Final answer should be with unit.

    For example-Carefully study the circuit diagram and find the value of resistor x.

    Ans. R = V/I = 6 / 0.4 = 15 ohm————– 1mark

    1/ R’ = 1/12 + 1/6 + 1/ 3 = 7/ 12

    R’ = 12 / 7 ohm…………………………………………… 1 mark with answer and substitution

    R= 15 = x + 12/7 + 2

    X = 11.28 ohm—————– 1 mark with substitution and final answer

    • In ray diagram-based questions/ numerical problems.

    Arrow marks should be shown in ray diagrams.

    • Object and image should be shown with arrow mark. (arrow mark denoted whether object/image is upright or inverted.)Understanding the fundamental concepts clearly can go a long way in scoring good marks. So, we recommend students focus more on this point.
      • Read the question paper carefully (Utilize the Reading Time allotted) and not jumble up the questions. You should be relaxed and calm while giving the exam.
      • Attempt all the questions in a proper sequence and with proper numbering of questions in the exam sheet.
      • Do not waste too much time on one question. Answer all the questions one knows and then focus on the remaining questions.
      • Keep an eye on the time as there are only three hours to attempt the theory paper.
      • Practice solving sample question papers in 3 hours before the main examination as this will improve the speed of handwriting and accuracy of answers.
      • Always analyze the answer sheet to avoid silly mistakes.
      • Ensure not to write more than what is required in an answer. Students can include examples and diagrams to illustrate the point in the answers (but only for 3-5 marks questions).It increases the visual appeal of the answer as compared to text presentation. In addition, keep the answers precise and to the point.
      • Diagrams to be drawn with a pencil only. Don’t use pen to draw diagrams.It is also important to study from the NCERT books and cover all the topics that are included in the syllabus.
         Tips For Chemistry

        Practice balancing the chemical reaction formulas.

        Learn the nomenclature of carbon compounds containing functional groups and the common name of salts.

        Do not miss ‘Saponification and Cleansing action of Soap’ as it is an important chapter from an exam perspective.

        Make a list of chemical reactions where the conversion takes place from one compound to another.

        Furthermore, it is important to follow the NCERT books and cover all the topics that are included in the syllabus.

          Tips For Biology

        • Almost every chapter in Biology has diagrams which the students need to practice well.
        • Ensure to remember all the important terms and their respective functions.
        • Get meticulous with the key definitions as the subject is mostly theory.
        • Knowing the weightage of each chapter is recommended to score better in the board exam.
        • Lastly, it is important to follow the NCERT books and cover all the topics that are included in the syllabus.


        How to Attempt the Paper

      •  Diagrams should be well labelled and labelling should be done on one side
      • only preferably right side. No colouring to be done in diagrams.
      • Avoid scribbling or overwriting as it will make your answer sheet look messy.
      • Strike off only once if you want to cut any information/word in your answer
