Following what I was saying in class yesterday about sample exam papers, here are a few things you can do online
Reading Test 1 p.10-12, answers p.13 and Test 2 p.14-16, with answers p.16
Writing Test 1 p.23-24 and Test 2 p.26-27; have a look at the corrected essays in the next few pages, they can be interesting for you to situate yourself
Use of English Test 1 p. 44-46, with answers p. 47 and Test 2 p.48-50, with answers p.51
Listening Test 1 p.56-58, Test 2 p.65-67
Speaking Test 1 p.79-81 and Test 2 p.83-85
the listening recordings can be found here
• There is also this one: it has free material as well as material you can pay for
So, decide on which paper you need to work the most, do it in exam conditions and tell me your results by email. If there is anything you are unsure about, let me know, I'll be at hand to explain. If you choose a writing paper, put it in my pigeon hole at school and I will try to correct it ASAP.
Good luck and go for it!
