I just realized that I may plan on going to study Linguistics further on and I missed the opportunity to take 1A03. Does it make sense to take 1AA3 then?
Will it hurt me second year not to take it now?
I'm also in soc sci am I able to take it next year?

Alot of questions I know

1A03 is the prerequisite for 1AA3 so you can't take 1AA3 without taking 1A03. It wouldn't hurt you if you take it second year. It's always offered in the summer so you can take it then if you want. These courses are open to all student in every facultiy; it't not restricted to one faculty at all
