CBSE Science Analysis, 2020

Analysis has been done of the paper, which was conducted in 2020.

Paper Pattern

Subject wise Marks Distribution

Paper Analysis

Overall, CBSE Class 10 Science Paper 2020 was of moderate difficulty level with few twisted questions. Nothing came out of the syllabus. Most of the students found Section B of the 3 markers to be the toughest of all. 4 to 5 questions were repeated from the previous year's paper. The only problem we could find is that questions were put in a little confusing language for students of 10th standard. However, students who had followed the NCERT Book and prepared well would have easily attempted all the questions in time and can expect a high score. The average range of expected marks by students is 60-70 Marks.Major Highlights
