Students Appearing CBSE Class 12 Board Exams 2020 : Follow these tips to score above 95 in Chemistry exam
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," says Vinita Vashist, Head Board examiner and Senior PGT (Chemistry) at Delhi Public School, Bulandshahr.
The Central Board of Secondary Education (CBSE) has released the Class 12 Board Exam date sheet 2020 (CLICK to download Date Sheet). Students have already begun with the preparations for their board exams 2020 as it is the high time.
Here The Kangla Times with India Today brings you highly experienced Head Board examiner Vinita Vashist, PGT Chemistry, at DPS Bulandshahr, with over 22 years of teaching experience and ten years of board examiner experience. She spoke to us about some tips for Class 12 students to score above 95 marks in CBSE Class 12 Chemistry Exam 2020.
"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.

Division of marks:
In Chemistry, out of 70 marks, 20 marks will be given to objective type questions which will include MCQs, paragraph based questions, assertion and reason type questions, and one-word answer type questions. Thus out of 70 marks, only 50 will be given to the subjective type questions where the students are required to write the detailed answers.
It seems that objective questions will be easier than subjective questions but the students must know that to answer these questions; they have to study each and every topic with proper understanding.
There are certain strategies that students can use to score above 95 in CBSE Class 12 Chemistry board exam 2020:
Preparation from NCERT is the most important part
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.
They need to practice all the intext questions, solved examples and exercise questions from all the chapters many times.
Generally, 5 marks questions are asked from the following units:
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.
Chemical equations from both organic and inorganic chemistry are easy to understand but difficult to learn. The only way to learn these equations is written practice. Students should practice these reactions by writing them as much as possible.
Before solving numerical questions, students should keep in mind the following things:
First, write all the information provided.
Next, write the formula.
Then put all the values with their units.
At last, instead of taking much time in calculations, leave space for the numerical value in answer, but write unit.
After completing the paper, do calculations for the final answer to the numerical questions.
Sometimes, students are too much involved in calculations, that later they fail to manage time and the entire exam gets affected.
Preparation of organic Chemistry
Students should write named reactions, tests to distinguish between compounds and conversions from all the units of organic chemistry altogether in the form of notes and then they should do written practice of them many times.
Preparation of inorganic Chemistry
Generally, three types of questions are asked from inorganic chemistry viz. to complete the equations, to draw the structures and conceptual questions. Conceptual questions and structures are easier to prepare than equations, so students should give preference to these questions.
"If there is an internal choice in the questions of inorganic Chemistry, give preference to structures and conceptual rather than to equations," said Vinita Vashist.
Preparation of tail chapters
Often we say that the last three chapters of 'Biomolecules', 'Polymers' and 'Chemistry in everyday life' are tail chapters. These three chapters are very scoring; students should prepare very short notes of these chapters in tabular form and should have a quick review of them. These notes are really beneficial.
Solving previous years' question papers
This practice is highly recommended. Students should solve the previous years' question papers like mock tests because while solving the question papers of previous years, students understand the time management and develop the temperament of facing the challenges of the exam.
Solving sample papers
Students should solve at least 10 sample papers of Chemistry if they want to score 95 plus marks. It will definitely improve their confidence and prepare them to face the challenges.
