Class 10 ICSE Biology Notes & Videos by Sir Tarun Rupani

The syllabus of  ICSE Class 10 Biology subject is vast, so studying the whole syllabus line by line by word can be very exhausting for some students. However, with Sir Tarun Rupani’s notes and videos, not only does the whole syllabus get covered easily, but it could also be revised many times before the board exam commences.

Class X ICSE Biology Notes

In a new initiative by Educart, we are providing free notes and videos of Sir Tarun Rupani who teaches all the subjects to Class 10 ICSE students. The notes are written by him to help students understand the concept more easily.
