A few years ago, CBSE class 10 boards were the first board exams of the CBSE students, and they’re used to be excitement and pressure among the students to score well. But since the Covid-19 pandemic started, situations have not been the same, and session 2020-21 boards were canceled.
For the year 2021-22, CBSE (Central Board of Secondary Education) has decided to change the format of the examination.

Know The Pattern of Class 10 Board 2021-22
For students of the batch of 2022, the board has decided to conduct two board examinations, Term 1 in November- December and Term 2, in March- April, like semester-wise examinations of college. The syllabus will be bifurcated approximately 50% for each term and the pattern of Term 1 will be multiple-choice questions, with Term 2 multiple types.

Clear Your Doubts Regularly
Do not hesitate to ask your doubts to your teachers. Online classes may seem different but you need to make the best use of them.
Solve Previous Year Questions
Solving Previous Year Questions gives you an honest idea about where you stand in your preparation. It helps you understand your strong and weak points. They are easily available online for your practice.
Regular Revision
Revise what you study regularly. It helps you retain your topics better and longer. Also, you’ll not have a load of topics to cover at the end.

-
Preparation Tips for Physics
- In Physics, formulae hold a very important place in the preparation. While you are studying, form notes of chapter-wise formulae, which will help you while practicing as well as to revise before the examination.
- We all are aware that numerical questions are asked in the physics examination. While some of them can be solved with just the knowledge of the formulae, other questions need practice. Practice these types of questions regularly, as they are scoring.
- Practice position-image diagrams of lenses and mirrors, solenoids, AC and DC generator, the human eye, Image formation of defected and corrected eye
-
Preparation Tips for Chemistry
- Understand the Modern Periodic Table, its trends, and learn the elements of the first and last two groups of the table. Also, study their electronic configuration.
- Memorise the common names, chemical formulae, uses of salts, and their compounds.
- Make notes of the reactions involving the conversion compounds.
- Practice equation balancing and understand oxidation-reduction.
- Learn the applications of acids, bases, and salts in general life.
- Questions are often formed from the reactivity series.
-
Preparation Tips for Biology
- Practicing the following diagrams is very important: different parts of the flower, male and female reproductive organs, Respiratory system, Digestive system, the human brain.
- Make sure you cultivate the habit of practicing diagrams regularly so that in the exams you could make neat and labeled diagrams.
- Understand the functioning of various systems of the human body, like the digestive system, respiratory system, excretory system, reproductive system, nervous system, etc.
- There are various terminologies in Biology which could be difficult to learn, but regular revision can help you ace them.
- Read the important definitions regularly.

- Read the instructions carefully.
- If you are not able to answer a question, do not waste your time on it. Do the other questions first, then if you have time left, come back to this question.
- Answer the question according to the marks allotted to a question.
- Draw a diagram wherever it is necessary with clean labeling on one side.
- Be careful about the time so you do not miss any question
Previous Year Questions
Chemistry
Ques: How are covalent bonds formed? (1 mark)
Answer: Covalent bonds are formed when atoms share pairs of electrons to gain more stability. For example, a chlorine atom has seven valence electrons. So, each chlorine atom needs one more electron to achieve a stable octet electron arrangement. As a result, two chlorine atoms will combine and share one pair of electrons that bind them together, called a single covalent bond
Ques: Mention the colour changes observed with reasons when:
(i) silver chloride is exposed to sunlight.
(ii) a piece of zinc is dropped in a copper sulphate solution. (1 mark)
Answer:
- When silver chloride (AgCl) is exposed to sunlight it is decomposed into silver and chlorine which is why it turns grey. This type of decomposition caused by sunlight is called photolytic decomposition.
- When zinc is added to a copper sulphate solution, copper gets replaced by zinc to form zinc sulphate as zinc is more reactive, due to which the colour of the solution changes from blue to colourless.
Ques: For the homologous series, whose 1st member is Methane, write the formula for the 2nd and the 3rd member (1 mark)
Answer: Ethane (C2H6) and Propane (C3H8)
Physics
Ques: A cylindrical conductor of length ‘l’ and uniform area of cross-section ‘A’ has resistance ‘R’. What will be the area of the cross-section of another conductor of the same material and same resistance but length ‘2l’? (2 marks)
Answer: resistance = length/ area of cross section
let r be resistance, l length, a area in 1st conductor and a' in 2nd conductor
In the 1st wire= r=l/a or a=l/r ........(i)
in the 2nd wire= r=2l/a'
a'= 2l/r
a'= 2a
Ques: Give reasons for the following :
(i) There is either a convergence or a divergence of magnetic field lines near the ends of a current-carrying straight solenoid.
(ii) The current-carrying solenoid when suspended freely rests along a particular direction. (2 marks)
Answer: (i) There is either a convergence or a divergence of magnetic field lines near the ends of a current-carrying straight solenoid because the strength of the magnetic field is higher near the poles /ends of the solenoid.
(ii) The current-carrying solenoid when suspended freely rests along a particular direction because a current-carrying solenoid behaves like a bar magnet.
Ques: Answer the following for a person suffering from myopia and hypermetropia
(i) What kind of lenses can correct this defect?
(ii) How are these lenses prepared?
(iii) A person requires a lens of power +3D to correct his near vision and –3D to correct his distant vision. Calculate the focal lengths of the lenses required for correcting these defects. (3 marks)
Answer:
(i)A person suffering from myopia and hypermetropia can use spectacles having bifocal lenses.
(ii) The upper part consists of a concave lens (to correct myopia) used for distant vision and the lower part consists of a convex lens (to correct hypermetropia) used for reading purposes.
(iii) GIven, P = +3D, f = 1 P = 3 1 m = +100 3 cm = + 33.3 cm, P = - 3DTherefore, Focal lengths of the lenses required to correct these defects.f = −100 3 = −33.3 cm
Biology
Ques: (a) Classify the following as homologous or analogous pairs:
(i) Broccoli and Cabbage
(ii) Ginger and Radish
(iii) Fore-limbs of birds and lizard
(iv) Wings of a bat and Wings of a bird
Answer: (a)
(i) Broccoli and cabbage are homologous because they belong to the same family
(ii) Ginger and Radish are analogous because they have different origins and perform the same function of food storage.
(iii) Forelimbs of birds and lizards are homologous because they have the same origin but perform different functions.
(iv) Wings of a bat and wings of a bird are analogous because they have a different form of structure.
Ques:
(a) State the role played by the following in the process of digestion.
(i) Enzyme trypsin (ii) Enzyme lipase
(b) List two functions of finger-like projections present in the small intestine.
Answer:
(a)
- Enzyme Trypsin: The pancreas secretes pancreatic juice which contains enzymes like trypsin for digesting proteins
- Enzyme Lipase: The pancreas secretes pancreatic juice which contains enzymes like lipase for breaking down emulsified fats.
(b) The finger-like projections in the small intestine are known as villi. The two functions of villi are:
- To increase the surface area of the small intestinal wall for more absorption of nutrients.
- And to absorb the protein molecules and help in the transfer of the proteins to all cells and tissues.
