This powerpoint presentation features 25 test-like multiple choice questions, 17 editing questions and 8 revising questions. Each slide includes a sentence that needs corrections or gives choices from which the correct sentence is chosen. In other words, there is no passage from which all the questions are taken. The correct answer and a brief explanation are included in each slide. The presentation works well as a "writing camp" test-prep activity, as an assessment, or simply as a teaching tool.
