Have you looked through the windows of your house in the morning to see the same few birds chirping and feeding their chicks at the same time each day? You might need an alarm to break your night's slumber every day, but those birds never seem to. You are just witnessing nature's circadian rhythm in action. Do you find the tiger, with its whole 200kg body walking through the night - stealthily enough to hunt a bear fascinating? Then you must dive into the world of biology to learn about nature and all its wonders. Whether you have difficulty with grammar, read a few classics and would like to learn more or want to practice your speaking fluency - I can help you with all things English. I am a post-graduate in biotechnology, with a specialisation in molecular oncology and pathophysiology from Jadavpur University, India. I completed my graduation in zoology. I can teach general biology up to the high school level. I can teach zoology and biotechnology up to the bachelor's level. Apart from the academic details, I have always loved reading books in English. That love led me to be a professional content writer for the last five years. I want to share my knowledge about this language to help you excel in yours.
