I am in my first year of GCSE's at high school and I really want to become a Zoologist or Marine Biologist when I leave school.

Currently I am taking Biology, Chemistry, English, Maths, Art, Geography, French and Spanish. I don't take Physics, will this be a problem?

At A Level and Higher I don't know if I am missing out anything crucial that would come as a disadvantage later on. I intend to certainly take Biology, but is there anything else I should definitely study?

Many thanks, Sarah

Looks like you have it pretty well covered but don't forget about "Earth Science" as that will relate to the environment that animals live in.
