NEET-2017 Botany Questions

Unit-I and Unit IV carries equal weightage in IPE For IPE this Unit got a weightage of 14 marks. Thre is no scope of Long Answer Questions. From chapter 9 & 11 Short Answer Questions are possible. From the chapter 10 ie. Biomolecules, Very short Answer type of questions will be asked. Student has to go through all the questions given at the end of each chapter. This year many questions are revamped and changed in the revised edition. Board of Intermediate Education did not give information regarding the change. Student must go through the new revised questions. Questions in the chapter 10 are also revamped. Students must prepare for the new revised questions. Diagrams are must for the answers as answers will be very brief. It is advisable to the student to attempt Short Answer Questions from this chapter to get more marks. In Unit -I for the SAQs much more information has to be written.
