I'm taking my second year of French. C'est comme ça ci comme ça. It helps a lot if you know Spanish, though. I'm guessing you don't have that advantage?
All you have to do is study and understand the sentence structure.
-adjective after noun, except for "petit" and some things like that
-"le" comes before most nouns. If not, "la." If it's plural, it's "des."
But I'm guessing you know that already. Still, it shouldn't be that difficult once you get the hang of it.
