Subject analysis
Science :
The CBSE Class 10th Science Exam was held on March 4, 2023. The science paper included three sets of questions papers, combining the topics of physics, chemistry, and biology. There were five sections in the question paper. The theory paper was conducted for 80 marks, and 20 marks were allotted for internal assessment.
SET -I
The set 1 question paper had a total of 39 questions that were categorized into five sections. Section A has 1 HOTs question, which carries 1 mark, and 19 LOTs questions. Section B also has 1 HOT question that carries 2 marks and 5 Lots of questions. Section C is filled only with LOTs questions. Section D has 1 HOTs of 5 marks and 1 LOTs questions. Section E has 1 HOTs of 4 marks and 2 LOTs questions. The chart presented above represents the bloom on the questioner. In set 1, questions have HOTs of 12 marks, while LOTS questions are worth 68 points. Blooms in the set 1 question paper are calculated to be 10% of HOTs questions and 90% of LOTs questions.
SET -II
The set 2 question paper had a total of 39 questions that were categorized into five sections. Section A has 1 HOTs question for 1 mark and 19 LOTs questions. Section B is filled only with LOTs questions. Section C has 1 HOTs question for 3 marks and 6 LOTs questions. Section D has 1 HOTs for 3 marks and 1 LOTs questions. Section E only has LOTs questions. The chart presented above represents the bloom count on the question paper. In the set 2 question paper, the HOTs question is for 9 marks. Blooms in the set 2 question paper are also calculated to be 10% of HOTs questions and 90% of LOTs questions.
SET -III
The set 3 question paper had a total of 39 questions that were categorized into five sections. Section A is filled only with lots of questions. Section B has 2 HOTs questions for 4 marks and 4 LOTs questions; Section C is also filled with only LOTs questions, while Sections D and E have 1 HOTs question each for 8 marks. The chart presented above represents the bloom count on the question paper. In the set 2 question paper HOTs question is for 12 marks Blooms in the set 3 question paper are calculated to be 10% of HOTs questions and 90% of LOTs questions.
Overall analysis :
The 10th CBSE question paper incorporates more LOTs questions, making it easy for the students to score 90%. Chapters like Chemical Reactions and Equations, Electricity, and Our Environment covered the most HOTs questions. The paper has a maximum of 4 HOTs with a total of 12 marks on average in each set. The majority of the questions were from chapters:
- Chemical Reactions and Equations
- Light – Reflection and Refraction
- Electricity
- Acids, Bases, and Salts
The average number of questions asked in each chapter is mentioned in the chat above. Least attention is given to the chapter “The Human Eye and the Colorful World”.
