To help you with your 'Target' work:
http://www.correctpunctuation.co.uk/
http://www.informatics.sussex.ac.uk/department/docs/punctuation/node00.html
http://www.uefap.com/writing/punc/puncfram.htm
While some of these sites are American (the last one features some on-line exercises, if you follow the instructions!), they should be comprehensive enough to help you focus on the specific target I set you. There are also other websites available. Good luck!
