What are some pictures or tricks that may help me remember biology facts better for my NEET UG preparation?

Okay, first you need to categorize your information.

Biology NCERT has following type of information:

1. Diagrams
2. Scientists and discoveries
3. Various types of diseases
4. Different values(like wt of liver, size of bacteria , etcetera)
5. The tables and cycles(glycolysis, Krebs, etc.)
6. The concepts

For diagrams, you have to go through them on a regular basis( say once a week or twice a month).
