CBSE CLASS-XII BOARD EXAM TIPS for chemistry by Rohit Raj Ranjan

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.

Written practice

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.

Solving numerical

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.
