Biology: Prepare Human Physiology, Plant Physiology, Cell Biology, and Biomolecules from Class XI syllabus according to previous questions in NEET and AIPMT examinations. Moreover, Animalia and Plantae must be given special attention as they are comparatively tough topics. The main emphasis, however, should be on characteristics of non-chordate and chordate phyla along with their examples. Also, memorise the common and scientific names of the organisms. Exercise as many numerical problems from Genetics as you can along with the pedigree chart. You must also establish a strong understanding conceptually about Biotechnology and Ecology.
