CBSE Class 10 Science 2019 Exam Review and Analysis

Difficult or Moderate? Definitely NCERT textbook-based.

By Admin 13th Mar, 2019 06:34 pm

After an easy and scoring Mathematics paper, CBSE Class 10 students appeared for the Science board paper today. Nervousness, exhilaration or just plain excitement... the response from students and teachers was varied. Most of the paper was NCERT textbook-based. While none of the sections seemed outright easy this time, students needed conceptual understanding to solve most questions in the paper. For the average student, the Science paper was a bit difficult.

Sections A to D had questions which were easy to moderate, but Section E, with questions that had to be answered through a practical approach, was a bit tricky and confusing. We can say that students needed to apply their mind to solve questions from the scientific concepts which they had learnt and revised throughout the last academic year.

Here we decode the CBSE Class 10 Science Paper for 2019 (Set 1) with all its elements and discuss the chapter-wise distribution of marks. But first we’ll compare the chapter-wise distribution of marks with the 2018 Science paper.

Chapter-wise Distribution (2019 v/s 2018)



The chapter 'Light - Reflection and Refraction' was the most valued chapter carrying 12 marks, followed by the chapters: 'Electricity' and 'Heredity and Evolution' with a weightage of 10 and 8 marks each, whereas the chapter 'Human Eye and Colourful World' did not carry any marks which was a bit of a surprise.

Practical-based questions were picked from the chapters 'Acids, Bases and Salts', 'Chemical Reactions and Equations', 'How do Organisms Reproduce', 'Light - Reflection and Refraction' and 'Electricity'.

There was a practical based question from Physics which took the form of a multiple choice question and yet needed some understanding of the concept of formation of image through mirror

General Observations

Listed below are some observations from every aspect of the paper with respect to typology, distribution of marks and, of course, difficulty level.

  • The paper had a moderate difficulty level, with Biology being easy but tricky. 
  • The Chemistry part was decently moderate, with most questions from the NCERT textbook. 
  • The Physics part was a bit moderate with application- and HOTS-based questions. 
  • A question from Chemistry 'State the reasons why carbon can…' seemed tricky as the solution was a bit fundamental.
  • HOTS questions, being a requisite for the CBSE board exams, totalled well up to 13 marks of the paper.
  • As expected, the practical based questions required much understanding and were a bit difficult.



Overall, the Science paper was neither too tough nor too easy and with many questions from the NCERT textbook. So, students should be able to pass the exam with flying colours. Also, students who went through our MIQs and sample papers would surely get above 50% marks in the paper.


It’s now time to focus on Hindi Course A and Course B. Team TopperLearning wishes you all the very best!
