Dear teachers!

I really need your help! The matter is that today my chief asked me to train a school leaver for entrance exams. I �m in despair, because we �re short of time: three months left till the end of a school year and the boy �s knowledge of English is satisfactory.� But, still I couldn �t refuse, because that child is an orphan and the boss begged me to help. So, could you be so kind to advise me where to start from, maybe some useful resources? Thank you in advance.�
