I have taken two years of IB Biology, which is a college level biology course. In general, I have taken biology all four years in high school and have done extensive research on many subtopics within biology. I have also taken the SAT Subject Test within biology and gotten a good score. If you choose me, I will be able to tutor you in any topic within biology as long as its high school level or lower, and we can negotiate scheduling. Message me if you have questions, thanks!
