COURSE STRUCTURE for Academic Session 2023-24:


BOOKS:
Weather I am providing STUDY MATERIAL to support, but you need to adhere with NCERT textbooks during your studies. National Council of Educational Research and Training (NCERT) provides text books according to recommendation of National Curriculum Framework (NCF). Although NCERT text books are compulsory for all subjects. Chapters are written in an easy dialogue style engaging the student constantly while some chapters are in the form of critical comments on the subject matter. I highly recommend NCERT book for CBSE exam, competitive exams, UPSC Civil Services Examination. Download the latest 2020-2021 Edition (for Exams in 2021) of NCERT Book.

Key features: 
  • Study material is prepared keeping in mind the needs of students studying in Class 10th CBSE and in such a way that students will be fully guided to prepare for the exam in the most effective manner, securing higher grades. 
  • The purpose of this material is to equip students with a sound knowledge of Biology at Class 10th Level. 
  • Study material is tabled in to detailed Notes, Videos and followed by certain exercises to make it student friendly. 
  • To make the students understand the chapter completely, each chapter has been divided into certain Modules. Each Module has been treated as a separate chapter.

How to draw diagrams in biology to score more:
To Drawing Biological Diagrams: A few rules to follow.
1. No need for Improvisation-
You can’t use your creative brain to draw biological diagrams on your answer sheet. You should draw what you see in the textbook, NOT what you WANT to see.
2. Use good Pencil-
