how about practising your third conditional skills before the exam? I will give you a situation (the consequence of something) and you will have to guess what happened, using a third conditional sentence, (if........., x....wouldn't have...) ok? Only one. the funnier, the better:
"the table was upside down when I came back home"
Hello my cheeky monkeys...here's another link I was told about by my colleague Laura, it's about London, going through all the situations you might encounter as a tourist there....it's got listening, conversation practice, grammar, phonetics....overall interesting. It's on the BBC page learning English, but here's a direct link to the activities...enjoy :-)
