C1 - Assignment 1

The results of the mid-module tests were, on the whole,  good. However, there were  areas of language competence that were below average for the level of English  you need to  reach :
1) Punctuation. Study sections 473-479 of Practical English Usage.  
2) Lexis. I would advise you all to  purchase and begin to  study Oxford Word Skills -Advanced, Ruth Gairns and Stuart Redman (OUP) . This is a self-study text.
