CLASS 12 CHEMISTRY Most Important Questions of NCERT 2020

CLASS 12 Boards

Central Board of Secondary Education (CBSE), this year made some important changes in the examination pattern of class 12. From introducing internal assessment in all subjects to changing the format of question paper for board exams, students must be aware of every minute detail of the changed examination pattern. As per the new exam pattern, CBSE has given more weight to the school-based/internal assessment. Major change will be observed in the questions paper format in the board exam 2020. Question papers will have more number of objective type question.

CBSE changed the examination pattern with an aim to

  • discourage students from rote learning
  • develop analytical skills and reasoning abilities among students
  • produce better results and improve the academic quality of institutions

I have given here some Important questions which is taken in accordance with the previous years papers.

These are important questions , means whatever you read ,you can give this a preference || Important questions doesn’t mean Guaranteed questions so please consider this .

Previous year I have Created similar kind of important questions and notes and 80-90% questions matches.

 NEW PATTERN

(a) All questions are compulsory.

(b) Section A: Q.no. 1 to 20 are very short answer questions (objective type) and carry 1 mark each.

(c) Section B: Q.no. 21 to 27 are short answer questions and carry 2 marks each.

(d) Section C: Q.no. 28 to 34 are long answer questions and carry 3 marks each.

(e) Section D: Q.no. 35 to 37 are also long answer questions and carry 5 marks each.

(f) There is no overall choice. However an internal choice has been provided in two questions of two marks, two questions of three marks and all the three questions of five marks weightage. You have to attempt only one of the choices in such questions.
