I have a general question about the MCPD exams. When i was revieweing the details of the exams,I ntoiced that some exams like 70-536 can be applied to more than one certificates. Does that mean i can start of by giving a 70-536 ,70-526 and 70-548 and getting a MCPD (Windows) and then later take only the 70-528 and 70-547 and get the MCPD (web).If so is there a time limit within which I have can apply credits taken?
