I am a life science enthusiast who has been teaching Biology to Medical aspirants for about 6 years now. This experience has made me realise that science should be narrated like a story by connecting each concept with a real life example. This not only makes the class fun & intriguing, but also enable students to connect everything that they learn in the classroom with whatever they see around them.
