Dear Suresh, I have cleared my DISA exam today. But I dont know exactly what are the chances in rechecking. But there is no restriction on the number of attempts.
The scoring of exactly 150 is because of the scaled marks system of ICAI.
Have you gone through the CISA questions while preparing for the exams. I think it is the best material available with us for study other then the ICAI Books.
