On March 7, 2020, the Central Board of Secondary Education (CBSE) held a class 12 chemistry test. The test was held across the country between 10.30 a.m. and 1.30 p.m. According to reports, 644552 regular students took part in the CBSE class 12 chemistry exam, which was held in 4774 locations across the country. The chemistry exam consists of both practical and theoretical components. The practical exams, worth 30 points, were held prior to the start of the CBSE class 12 theory board exams. The chemistry paper in CBSE class 12 is worth 70 points.
Under the Science stream, the CBSE board administers the Class 12th Board Chemistry Exam. The theoretical paper is worth 80 points, while the project work is worth just 20. Chemistry is a crucial topic for students in the science stream. Previously, students who took the Physics exam considered the paper to be extremely difficult and lengthy.
CBSE made several improvements to the paper pattern last year, with section A containing 20 one-mark questions and sections B, C, and D containing two-mark, three-mark, and five-mark questions, respectively. Furthermore, there was an option between sections B, C, and D on an internal level.
Students’ Analysis of the CBSE Class 12 Board Exam Chemistry Paper 2020:
The chemistry paper for CBSE class 12 is divided into four parts, each with a different weightage. When compared to the CBSE class 12 physics exam, students who took the CBSE class 12 board chemistry exam said the difficulty level of the paper was between easy and moderate. The exam could be completed in a reasonable amount of time, and most students selected section C as slightly more difficult than the other sections. Section A, which included multiple-choice questions, was also simpler for some students, while section B, which included assertion-reasoning questions, was slightly more difficult.
Only questions from the prescribed syllabus were included in the chemistry exam 2020. The pattern and difficulty level of questions in the CBSE chemistry paper 2020 were very similar to the CBSE class 12 chemistry sample papers published by the board.
Chemistry Paper 2020 for CBSE Class 12 Board Exam – Teacher’s Review:
One of the teachers accepted that logic problems necessitated a deeper understanding of principles, while numerical and chemical equations were simpler to solve and did not take much time. Some teachers have said that the chemistry paper had simple questions, with approximately 70% of the questions taken directly from the NCERT textbooks’ prescribed syllabus. The majority of teachers who reviewed the paper shared the common point of the paper being easy to solve. This opinion of the teachers largely stems from the fact that up until 2019, the board papers for the science stream were prepared in a different and much tougher way. Due CBSE changing its patters of preparing the paper, students in 2020 faced a major advantage and better chances than their predecessors
Chemistry Paper Pattern for CBSE Class 12 Board Exam in 2020:
This year’s CBSE class 12 chemistry exam pattern has changed slightly. There were a total of 37 questions in the report. The CBSE chemistry paper for class 12 students in 2020 was divided into four sections:
Section A consisted of 20 questions with very brief answers or multiple choice options. Each question is worth one point.
Section B – This section consisted of seven short answer questions, each worth two points.
Section C – This section also had seven short answer questions, but each question was worth three points.
Section D – The final section contains three long-answer questions worth five points each.
While students were not given any overall choices, they were given internal choices within sections B, C, and D, as shown below. Section B had two questions and so did section C. There were options for all three questions in section D.
In the list given below, the mark weightage of questions from various chapters of the prescribed CBSE chemistry syllabus 2020 is shown:
- Solid State: 4
- Solutions: 5
- Electrochemistry: 5
- Chemical Kinetics: 5
- Surface Chemistry: 4
- General Principles and Process of Isolation of Elements: 3
- p-Block Elements: 8
- d- and f-Block Elements: 5
- Coordination Compounds: 3
- Haloalkanes and Haloarenes: 4
- Alcohols, Phenols and Ethers: 4
- Aldehydes, Ketones and Carboxylic Acids: 6
- Organic Compounds containing Nitrogen: 4
- Biomolecules: 4
- Polymers: 3
- Chemistry in Everyday Life: 3
