'Should be able', i'm sure if you walk around and ask people, not everyone will be able to get it correctly T_T

Go to school if you don't know what A levels are. Multi.

I go to school in America and I don't even know what your "A" level is (btw, you being in Chem means you should know for sure). All I know is i've taken Honors Chem and Advanced Placement Chem.

A levels are British. Stands for Advanced levels. They are a qualificiation but usually are used for entry into university courses.
