With new syllabus being introduced for the first time in EAMCET question papers it is the long term students rather than regular students face difficulty in last hour preparation and revision for the exam.
 
 
 For the convenience of the student for a better preparation and revision, at this hour of examination time, in Botany subject the entire subject can be divided into parts. As the topics of the Botany are not properly arranged for better understanding of the subject it is difficult for a comprehensive division into parts
 
 . The first year syllabus is divided here into three parts viz Units-I & II; Units- III & IV; Units-V, VI & VII. Similarly second year topics also divided into Unit-I; Units-II & VI ; Units- III, IV & V . A student can club first and second year topics for preparation according to his convenience.
     
 In the Unit- I of first year basic features of different plants groups are discussed with much ambiguity. This unit very important for the exam point of view. Unit-II is comparatively much easier and questions are also straight with no difficulty.
