Tips to Succeed in NCERT Class 11 Chemistry Exam

1. Practice from sample papers and papers from past years.

Examiners follow a pattern of recurrence for certain important questions across multiple years, which is why going over past years' papers is so crucial. While you're at it, make a note of the essential parts and recurrent concepts so you can go over them the day before your exam. 


2. The most essential aspect is preparing from NCERT textbooks.

Questions and concepts from NCERT textbooks make up a large part of the CBSE exam exams. Cover all topics, including diagrams and graphs, followed by solved examples and exercise questions, in order to ace your Chemistry paper. Keep a reference book beside your NCERT textbooks for instant clarification on complicated concepts, and continue to mark the essential and tough questions as you go. Because the number of questions might be daunting at first, start with the chapters that carry the most weightage in the Class 11 Chemistry examination. 


3. Pay Special Attention to the Numericals, Reactions, Formulae, and end products.

When taking any exam, time is a key limitation. While tackling a detailed question may appear achievable at the time, it not only takes a long time but also does not guarantee full marks at the end because you may miss out on some keywords or crucial points while compromising on other answers.

Keep the following additional tips for the Chemistry exam in mind-

  • Practice as many numerical problems from chapters like 'Electrochemistry' as you can.

  • Concentrate on Organic Chemistry naming reactions.

  • In chapters like 'p-Block Elements' from Inorganic Chemistry, the product, characteristics, and anomalous behaviour must be highlighted.

  • Mention names of reactions such as Williamson, Wolff-Kishner, Hell-Volhard-Zelinsky, and Clemmensen reduction in the Chemistry exam. 


4. Excellent writing abilities are essential.

There is typically a lot of information to write within the given 3 hour time limit. Writing and solving equations improves your speed and confidence while also teaching you how to recognise the keywords and highlights that should be included in a solution. In Organic Chemistry, stating the names of the reactants and products boosts the solution's authenticity. A student's ability to produce neat work is a non-negotiable asset.

Always attempt to give extensive and informative explanations in points, followed by labelled diagrams that serve as visual assistance. A tabular format should also be used for a comparison study. These minor details may help your answer script stand out from the others.


5. Fetch full Marks in Scoring Chapters

'Biomolecules,' 'Polymers,' and 'Chemistry in Everyday Life' have all been recognised as leftover chapters worth 10 marks each that the majority of students ignore. These three chapters, on the other hand, have the potential to be quite high-scoring. Students can make brief notes in a tabular format from these chapters so that they can review them during the last week of the Class 11 Chemistry examination without losing time for more essential and complicated topics.


6. Self-assessment

The anxiousness that develops when studying and preparing for a test is an unavoidable aspect of the examination process. It's normal to be irritated by your lack of preparation or inability to accelerate your learning pace, but you can't make yourself feel guilty about it. Instead of feeling sorry for yourself, you must identify your shortcomings and dedicate more time to addressing them. By assessing your shortcomings and working towards improving on them, you too can master the Class 11 Chemistry syllabus to fetch high marks in the final examination. 


7. Effective Time Management

The reading time of 15 minutes during the examination is the most important and should be spent wisely. If you're stuck on a question, skip it for the time being and attempt questions whose answers you are aware of. A few experts have also encouraged students to save Organic Chemistry questions till the conclusion of the examination because they are more complicated than Inorganic and Physical Chemistry. Always plan your time so that you have a 15-minute time in the end to revise your answers. 


8. Get Adequate Rest Before the Exam

It's not uncommon to see students studying till the early hours the day before a test! Why would you want to go without sleep in the days coming up to the exam? Rather than depriving yourself of sleep, prepare so thoroughly (for the exam) that you can have a good night's sleep the night before and will be able to perform well in the exam with a well-rested mind. 

By diligently following the tips mentioned above, you are bound to succeed in the Class 11 Chemistry examination by fetching high scores.
