Biology is a vast subject relevant to many fields. I can provide explanations of biological concepts for people with no background (i.e. if you need it for your work), for school students struggling with their lessons, and for students interested in biology who would like to pick a medical or biological career. I can also help with understanding biology holistically, not being separated into seemingly unrelated areas like "botany" or "anatomy". In my experience, this helps with remembering facts better, understanding the concepts, applying your knowledge to the everyday life problems and falling in love with biology.
