Types of Questions from the CBSE Syllabus for Class 11 Maths 2023-24

Due to pandemic, there were adjustments to the syllabus for class 11 maths. Though small changes have been made this year. 

• Typically, for a Maths test, you will be given a variety of questions based on the CBSE Class 11 Maths syllabus. 

• Aside from that, you'll be asked memory questions. These types of questions assess your understanding of fundamental concepts, your ability to recall previously taught things, and your memory. 

• You'll also be asked questions based on your knowledge of the subject. Based on the following criteria, you will receive 55% of the questions. 

• A problem based on the application of a specific notion or theorem is another sort of problem. About a quarter of the questions are application-based. 

• Another 20% of the questions are dependent on your ability to analyse a situation.
