On the day i took my toefl ibt (25/08/07), my mouse developed a fault in the course of the test .I signified by raising my hand and an invigilator came in response to my sign(my risen hand).I informed him of what had happened then he changed my mouse.While he was changing my mouse,the time for that part of the reading section elasped.Because I was still on my 19th question out of 28 questions,I missed 9 questions in the reading question.I just continued with the next set of questions that came after the 28 questions.Later,my mouse got faulty again I was transferred to another computer to continue from the question I stopped at.But I am worried about the 9 questions I missed due to the fault of the mouse in the test centre.Now,I am not certian of the score I could get because of this mouse fault in the test center.It is unfair that I should suffer or pay for something that I am not responsible for.Please what should I do to ensure fairness ?Who can I complain to?
