I have been teaching and tutoring now for almost 5 years. I specialize in teaching Biology, however, I have taught Chemistry, Physics, Psychology, and English as a foreign language. From 2018 to 2019, I taught biology and psychology at college/ A level; I love teaching college level as I really get to explain the more intricate details for some of my favorite subjects. In these 5 years of teaching, I also did some private tutoring for A level Biology.
I love teaching science and look forward to teaching you. At present, I now teach English as a foreign language. I absolutely love this job as I interact with a range of culturally diverse people. I teach English as a foreign language online to people all over the world.
