The Central Board of Secondary Education (CBSE) will be releasing the Class 12 date sheet 2020 in the month of January.

This year, CBSE has introduced big changes in the pattern of the question paper. The question paper will have a number of objective type questions. The aim of this change is to discourage students from rote learning and to develop analytical skills and reasoning abilities in them.

In chemistry the question paper is entirely based on the content from NCERT book, so the students need to prepare from NCERT. They should go through the entire content, every diagram, every graph, explanation under the diagram, footnote, etc.

Important units

Generally, 5 marks questions are asked from the following units:

1. Electrochemistry

2. Chemical kinetics

3. P block elements

4. D and F block elements

5. Aldehydes, ketones and carboxylic acids.

Students should concentrate more on the above-stated units.
