Scoring Topics for Class 11 Physics Exam

Class 11 is the most crucial stage in every student’s life. Your teachers prepare you for your class 12 boards. You will learn many new concepts and topics in detail that will directly help you in your 12th class. If you want to score a good percentile in your 12th boards, you must not take your 11th class lightly. The knowledge you will gain in your class 11 will help you immensely in class 12th. Almost every topic you will see in the class 12 curriculum is connected directly with the knowledge you will gain in class 11. However, you will need to work hard to understand each concept and topic in depth.

Physics is a very crucial subject you will come across. This subject is not only for your 12th board but will also help you with your competitive entrance exams. This subject plays a vital role in adding your scores to your competitive exams. Physics is a subject comprising logical reasoning questions. It explains the frequency and velocity of how the things around you are happening. A depth study of this subject can help you open up your imagination. It also enhances your thinking ability. 

Before knowing about the scoring topics, you must read and understand the marking scheme of the Class 11 Physics exam. This marking scheme and pattern are according to the CBSE, which gets revised every year. Always check for recent updates before starting your preparations. It will help you to put your efforts and hard work in the right direction. 

The exam pattern for the Class 11 Physics annual exam is as follows: –

  • Section A– This section comprises Very Short Answer Type Questions that are usually 5 in number. Each question carries one mark.
  • Section B– This section contains Short Answer Type Questions (I) that are usually 5 in number. Each question carries two marks.
  • Section C– This section also contains Short Answer Type Questions (II) that are 12 in number. Each question carries three marks.
  • Section D– This is the Value-Based section where you will get questions related to the values. This section contains only one question that carries four marks.
  • Section E– This section will comprise the Longer Answer Type Questions. The number of questions in this section will be 3, and each question will carry five marks each. 

After knowing the marking scheme and pattern of your Class 11 Physics exam, you must know the topics that are essential and high scoring. 

Some of the essential scoring topics are there in your class 11 CBSE course. These topics can surely help you to score good grades in your class 11.
