To score good marks in this, students are required to perform well in all three sub-divisions of Science; Physics, Chemistry and Biology.  To help students prepare in a better way for the exam we have provided here the last minute preparation tips for Physics, Chemistry and Biology sections of CBSE class 10 Science. These tips will definitely work for all students in their preparations and build confidence in them to do well in their CBSE Class 10 Science Exam 2020.

Important Points to Keep in Mind for Writing CBSE Class 10 Science Paper Flawlessly  

First of all let us know the weightage distribution of three-subdivisions for the CBSE Class 10 Science Board Exam 2020. According to the CBSE Class 10 Science Latest Syllabus, the unit-wise marks distribution is arranged as follows:

  • Unit 1 Chemical Substances – 25 Marks
  • Unit 2 World of Living – 23 Marks
  • Unit 3 Natural Phenomena – 12 Marks
  • Unit 4 Effects of Current – 13 Marks      
  • Unit 5 Natural Resources – 07 Marks

Unit 1 comprises all chemistry chapters, unit 2 and 5 both cover the Biology chapters while units 3 and 4 include all chapter of Physics. Thus weightage distribution across three sub-divisions comes out to be as follows:

Sub-division
