Hi Sandeep. It all depends your style of studying. As you'll see mentioned in some posts, some candidates included flash cards in their study arsenal while others didn't. Flash cards are a good resource to study concepts in small volumes conveniently, like during your lunch break at work.
Do I need to purchase the Hot Topics PMI-ACP Exam Flashcard? I have Mike's book and the AGILE prepacst. I have also read throught the Agile headfirst book.
