Hello Meena,
Based on how you have described your situation: Yes. I think so.
But please keep in mind that you must earn a minimum of 8 PDUs in technical PM, 8 in Leadership and 8 in strategic and business management. The Agile PrepCast will give you a total of 40.5 PDUs and they are divided as follows: 32.5 technical, 6 leadership, and 3 strategic.
This means that if the 21 PDUs that you already earned include 2 PDUs in leadership, and 5 in strategic then you are good to go. If not, then you will have to earn these specific PDUs separately.
