I need to revise spanish but have no idea where to start... any ideas??
In order to revise for Spanish - I would suggest listening to Spanish radio and reading Spanish articles and books (and see if you can translate them into English). If there is a photograph, try and figure out what the words mean by looking at it.
I did this and got an A* at GCSE level.
Duolingo is definitely useful. Past papers do help too. I always think the listening papers give too long a pause between questions so they'll help you get used to that also.
