[Wiggles 123]

I want to be a graphic designer or an art director in advertising when I'm older and I'm about to to leave secondary school and I haven't got a clue of what 4 courses to take at college, so can you please help.
P.S. If you could write 4 ideal courses for the jobs separately that would be amazing !!
