I'm also doing Beginners Spanish and AA100, starting in October. I didn't do Spanish at GCSE or A Level but lived in Spain last year for 5 months, everything I know is self taught.
I'm not really sure what's in store but I'm just trying to get prepared at the moment. I've been through the Induction and I'm going to order the set books next.
What do you mean by creating a group? Facebook or something else?
