I assume that this is an organization for intellectual individuals, of which I am one.
My knowledge is a bit less in science than other areas, but still rather advanced for my age, which is 13. I am in our 8th grade accelerated biology class, in which I have learned college level human biology, such as tracing the body's blood flow, digestion, and respiration. I am also proficient in zoology, being able to tell you information on many different animals, whether they are terrestrial or aquatic. Basically my specializations are within the sciences of life. I could also do some geography, if by that you mean earth science.
Thanks.
P.S. If you plan on adding a physical science area, I would like to strongly recommend Meamme0 for both that and chemistry. He is in a physics university and has had several advanced chemistry classes as well.
