hi Rishi, If i'm correct Sun conducts beta test,when introducing new exams or while changing the exam objectives or when introducing new format for the exams. I remember i took one beta exam for scjp2 during last Aug.As far as for scwcd,the beta exam is available no more. Frequent visit to javaranch or http://suned.sun.com/US/certification/java/index.html may help to know the schedules of beta exams. regds. swaminathan.
