Studying Spanish A Level OnlineWatch
I have been studying Spanish on and off for some years and I had already covered most of the grammar at some point (not that that means I can remember it!) so I really focussed on vocabulary. I use anki to make flashcards and over the length of the course I made cards for nearly 3000 words. Not just the ones in the text book lists, but any new words I come across from watching Spanish TV shows, reading books and news sites etc.
It is really hard to practice speaking when you're not studying as part of a class. Quite close to my oral exam I joined a local community Spanish-English intercambio group to practice, but I really wish I'd done that earlier so I recommend doing this as soon as possible if you have something similar near you. Another option is to look on italki for someone who wants to practice their English in return and then you can do skype exchanges. Unfortunately there are some dodgy guys on there so you need to be careful, but I did meet one person who was genuinely interested in learning and has become a good pen pal.
For the literature part you will study the play La Casa de Bernarda Alba. As well as the Hodder guide that is suggested by NEC.
It has parallel text in Spanish and English which was handy as some of the Spanish is tricky, but mainly because it has absolutely tonnes of notes and discussion about the themes, characters etc. I am no good at literature analysis and this book helped me so much.
It's worth watching the film (Volver) and reading the play early on so you have time to take them in and think about them, don't leave it to the last minute.
