Biology is a sub-section of GAT paper in NDA examination. Biology contains almost ten to twelve questions in the examination. Since, NDA candidates are mostly from PCM stream and Biology is a new kind of subject for them. It became important for them to practice it as much as possible. Well the good thing is, NDA examination syllabus of Biology doesn’t go into the deep of this subject; a student can prepare well for Biology from NCERT 10th class book only. Even though the syllabus is easy to handle for an NDA aspirant then also it is very important to keep a regular touch on it and practice it more and more.
Here we are providing some important questions for Biology based on previous year NDA examination paper.
