Hello
Please note that I have published some documents that you should see.
First of all I shoud mention the test plan.
Then you can practise your grammar skills by doing some online exercises on the Passive Voice and the Future Tenses. As for your Writing skills check the box on your right-hand side to refresh your memory.
Finally, and as you read an extract of the book WHITE TIGER by Aravind Adiga I'd strongly recommend you to read, and listen to, his interview to The Guardian.
