• Dear Dr..Prabhakar
    Thank you ever so much for your comments.Of course  the percentage of students  who had received zero marks was only less than  2 percent of the student population. Having had five years of schooling, a student face an exam where the child obtain just zero marks is worth investigating. That is why I did 19 case studies where I gathered students’ data related to students’ family back ground , School, Class, teachers, peers, social factors etc.As you suggested, I have collected those qualitative data. At this moment I am writing the case studies and the main report. Once again thank you very much for your comment
     I would lik to share my main findings soon
