I understand that some of you may be tired of editing exercises, but this is a way for you to know how familiar you are with grammar, idioms and some collocations in the language.
Below is an exercise I took from ddem2000 (http://instagram.com/p/nfkMzrEkq2/). I hope this reminds you that you can have fun while editing!
Note: There can be more than 1 mistake in each sentence, and there can be none. Feel free to comment on the Sentence Structure as well.
