Difficulty Level and Typology of the Question Paper

The sample question paper released by the Board contains questions which test the understanding and practical application skills of students. The paper includes the following types of questions:

 

Section A — 1 mark questions: MCQ, VSA and assertion-reason type questions

  • This section includes all possible types of very short answer questions: define, give reason, state the principle, state the law etc.
  • Questions can also be framed based on a diagram, a paragraph, a graph or tabular data. This requires that you analyse the given data carefully, apply your understanding of the concept and arrive at the answer.
  • Multiple choice type questions can be easy to answer provided you are thorough with the concepts.
  • A new type of question ‘Assertion-Reason type’ has been introduced from this year. Assertion means a statement and reason means an explanation about that particular statement. You just need to understand the statement to give the right answer. You can easily score marks in these questions.

 

Assertion: A fuse wire is always connected in parallel with the mainline. 

Reason: If a current larger than the specified value flows through the circuit, the fuse wire melts.

 

Section B — 3 mark questions: SA type questions

  • This section is a combination of questions which include the remembering, understanding, application and evaluation type.
  • If you carefully analyse the sample paper provided by CBSE, you will notice a new typology of question being introduced, which is the ‘Creating’ type.
  • In these types of questions, you need to compile the information in a different way by combining elements in a new pattern or proposing alternative solutions.

 

(i) Create a terrestrial food chain depicting four trophic levels.

(ii) Why do we not find food chains of more than four trophic levels in nature?

OR

How will you create an artificial aquatic ecosystem which is self-sustainable?

 

Section C — 5 mark questions: LA type questions

  • This section comprises questions which are mostly numerical problems in Physics and Chemistry and require a problem-solving approach to deduce the final answer.
  • You need to reason out every question in order to score well in this section.
  • In Biology, expect diagram-based questions or questions to describe a process in this section.
  • Focus on writing precise, point-wise answers to save time and score full marks.

In short, we can say that the Science sample question paper for Class 10 which has been published by CBSE has a higher difficulty level with more focus on applications in day-to-day life. Students should keep in mind that understanding of concepts and their applications is key to score well in the CBSE Class 10 Science paper.
