I took re- admission in cbse class 12 and changed my subject from maths to biology. Will I have to give practical exams of all subjects again or only biology?
Greetings,
if you are taking re-admission then you have to go through everything all over again with your new subjects which includes practical exams for all the subjects in your syllabus.
good luck
I scored 84.6% in CBSE class 12 in the year 2020. So what is my percentile
If you are from PCM background the approximate percentile score of you would be 78-79 percentile. percentile is nothing but the percent of values below a specific value. This means you've performed better than 78 - 79% of all the students (1016719 [excluding absentees]) that took the same exam.
Hope it would be helpful.
imp topic to pass cbse class 12 bord exam 2021 for physic & chemistry exams
Greetings!
Chemistry:
Unit-I - Solid State
The questions are likely to be asked on the metallic solids in the classification of solids based on different binding forces, numerical problems on the calculation of density of unit cell and electron sea model.
Unit-II - Solutions
Students can expect one mark questions on types of solutions. The other important topics are Henry's law, depression of freezing point, Van't Hoff factor and osmotic pressure.
Unit-III - Electrochemistry
One can expect one mark questions on conductance in electrolytic solutions and Kohlrausch's Law. The Faradays' laws, lead accumulator and standard electrode potential are important.
Unit-IV - Chemical Kinetics
The rate of reaction, concept of collision theory, effect of temperature in activation energy, Arrhenious equation and concept of collision theory are very important.
Unit-V - Surface Chemistry
The adsorption - physisorption and chemisorption are very important along with Tyndall effect and Brownian movement. Students should also focus on types of emulsions.
Unit-VI - Isolation of Elements
The principles and methods of extraction - concentration, oxidation, reduction are very important.
Unit-VII - p-Block Elements
In the Group 15 Elements, the conceptual questions are expected this year from compounds of Nitrogen and preparation properties & uses of Nitrogen. The same goes for Phosphorus as well. The questions on Ozone, Sulphur and Sulphuric acids are expected in the Group 16 Elements. While coming to the Group 17 Elements, compounds of halogens and oxoacids of halogens are crucial.

Read the nomenclature, nature of C-X bond, optical rotation and uses & environmental effects of - dichloromethane, trichloromethane, tetrachloromethane, iodoform, freons and DDT.
Unit-XI - Alcohols, Phenols and Ethers
Read thoroughly the nomenclature, methods of preparation, uses and properties of Alcohols, Phenols and Ethers.
Unit-XII - Aldehydes, Ketones and Carboxylic Acids
Not much important in this unit. However, give special attention to carboxylic acids uses and mechanism of Nucleophilic addition.
Unit-XIII - Organic Compounds containing Nitrogen The Amines
methods of preparation is the most important besides identification of primary, secondary and tertiary amines. The chemical reactions and importance in synthetic organic chemistry is also important.
Unit-XIV - Biomolecules
The classification of aldoses and ketoses, denaturations of proteins, classification of vitamins and nucleic acids - DNA and RNA are important.
Unit-XV - Polymers
Give utmost importance to the methods of polymerization, copolymerization and bakelite.
Unit-XVI - Chemistry in Everyday Life
In the chemicals in medicine, focus on antibiotics and antacids. In the chemicals in food, give importance to artificial sweetening agents. However, soaps, detergents and cleansing action are important in the cleansing agents.
I hope this was helpful. Thank you!
