Hey, I did this exact course 2 years ago. I was given SO MANY A4 sheets of all the vocab, and it may sounds funny, but my mum and I decided we would learn them all together. So, everyday from about now. she would test me on 10 words, then again the next day the ones I got wrong plus a new 10 - with us both learning and testing each other - it made it less of a chore.
We did Virgil and some Pliny for our verse section - and I honestly tried to learn the translations in english, because then in the exam when it asks you to translate a section, you can. also - look at past papers to see if there's anyway you can guess which few may come up and really study those ones - although make sure you study them all!
Roman Life - for us this was only a 45 minute paper and was about 20% of the exam, plus the whole thing is in english, so don't stress too much over this section! Try and write out the main facts on each topic, learn them, maybe write a few essay's and stuff - hopefully you'll find this the easiest paper!
But yea - all I can really say is start learning vocab now - you'll be sick of it come june, but it's so worth it! Good Luck!
