Physics, Chemistry, Maths, and Biology of Class 11 are quite different from what students have studied in Class 10. The level of difficulty is higher. New chapters, concepts, and topics are added to the Class 11 syllabus, which means a deeper understanding of topics.

Compared to Class 10, Class 11 needs a lot more knowledge of theories, formulas, visualisations, etc. Moreover, questions asked in the exams are not direct anymore. So, one must prepare accordingly. Let us now see in detail the CBSE Class 11 preparation plan.

Physics is a subject with specific central theories and principles upon which the other theories are based. So, the CBSE Class 11 Physics syllabus must be finished with utmost seriousness.

- Read the Class 11 Physics textbook thoroughly. Understand the chapters clearly – every single concept without skipping anything.
- Remember, students must visualise the various mechanisms, processes, experiments, etc. This is very important when it comes to Physics.
- Refer to one or two of the top reference books for Physics. For example, students can study the Class 11 reference book to improve their conceptual knowledge of Physics topics.
- Note down the important points for every chapter in a separate notebook – definitions, short descriptions, formulas, diagrams, equations, etc.
- Understand the steps to solve problems from the example problems.
- Solve practice questions at the end of the chapter. Mark difficult questions to revise/practice them later.
- Students can practice unlimited questions for Class 11 Physics at Embibe for free. The practice questions have been prepared from several reference books online.
- Students can then take the mock tests at Embibe to track their progress, check the feedback from Embibe’s AI assistance, and earn Embiums.

The CBSE Class 11 Chemistry syllabus has three parts – Physical Chemistry, Inorganic Chemistry, and Organic Chemistry. Physical and Inorganic Chemistry is comparatively easier than Organic Chemistry, which has topics on chemical reactions.

- Refer to NCERT Class 11 books at Embibe to understand every concept, topic, mechanism, process, reaction, etc.
- In Chemistry, students need to remember a lot of formulas, reactions, equations, etc. So, jot down the equations, reactions, and formulas.
- Write down the definitions of various terms and short descriptions of various processes, reactions, experiments, etc.
- Practice the reactions and equations regularly; otherwise, there are chances students will forget important points.
- Get an idea about how to solve problems from the example problems.
- Solve chapter questions and previous year’s question paper Class 11.
- Revise the theory, equations, reactions, and formulas regularly.
- Students can study all the topics from Chemistry at Embibe as well. Embibe has all the relevant study material a child needs to ace the exams.
- Students can read books at Embibe and watch fun learning videos to understand the concepts better.

Mathematics is an important subject for engineering aspirants. This subject needs one to remember a lot of formulas. However, remembering the formulas without understanding their theory is not recommended.

- Refer to the NCERT Class 11 books at Embibe and understand the theory behind every concept and topic.
- Jot down the formulas for each chapter and understand what they mean, and practice their derivations.
- Remember the formulas by regularly studying them.
- Go through the solved problems to understand the steps to solve them. The RD Sharma Class 11 book is good for understanding how the sums have been derived.
- Solve the questions at the end of the chapter. For Maths primarily, the more students practice, the better they get. Also, with practice, students will discover and learn the various shortcuts and tricks to solve problems.
- Students can watch the videos at Embibe to learn all the complex concepts. They can also practice questions on various theorems and put their learning to test as well.
- Students can take the free mock tests and solve the questions available at Embibe anytime online.

Biology is essential for medical aspirants. It is a theory-based subject, and students must remember many diagrams, processes, scientific names, etc.

- Read the various concepts in detail from NCERT Class 11 books for Biology.
- Write down the important terms, points, short descriptions, diagrams, flow charts, scientific names, etc.
- Every time students finish a chapter, they must solve Embibe’s practice questions. Then, revise them regularly, both theory and the questions.
- Students can understand all the Biology concepts for Class 11 at Embibe. Embibe offers 3D videos, NCERT Exemplars, model papers, books, and much more. Students can refer to them and take the mock tests to get appropriate feedback by the AI system.

During CBSE Class 11 preparation, remember the following points:

- Know the syllabus thoroughly. The syllabus of Class 11 is elaborate. Students should be thorough with the syllabus before preparing for their lessons.
- Prepare a timetable considering the areas of strength and the time students want to dedicate to the topics. Stick to it.
- The Class 11 final exam will have mostly theories and fewer numerical questions. So, students have to prepare for that as well. Make notes of various definitions, short descriptions, experiments, etc. Students must be able to write the theories for every single concept.
- Refer to previous years’ papers and sample papers at Embibe to get an idea about what kind of theoretical questions are usually asked and make notes. Solving the question papers at Embibe will also give an idea about the exam pattern, the difficulty level of questions asked, important topics, and so on.
- Students must also solve numerical problems at Embibe for every subject diligently.
- After completing their school exams, most students tend to attempt competitive exams. Since the syllabus of the exams and the board finals have a lot in common, students tend to focus on reference books at Embibe for their preparation. While that is a good practice, students should not leave out the NCERT books available at Embibe. The NCERT books will help to strengthen their foundation of the topics.
