  2. Students need to focus on topics related to developments in India in Economic Zoology.
  3. Practical Bio-chemical pathway with structural formula of molecules are important.
  4. Prepare from medical bio-chemistry and physiology books.
  5. Represent most information through flow charts.
  6. Always draw relevant anatomical diagrams.
  7. If physiology and biochemistry are prepared thoroughly, then this part can be prepared only for short notes.
  8. Coloured drawings are a must. Students need to practice them properly.
