I read only PMBOK, notice that I am already certificated associate in project management CAPM

Thank you, Fahad! What book or materials did you planned your study and any insight is greatly appreciated.

Do you want to answer the questions during the real exam with 100% confidence that you going to pass?

that what happened to me today

simply by two steps

1- understand what project management mean by Process group not knowledge area
Aileen Ellis, she is the best to provide this knowledge
2- Solve not less than 3000 Questions based on process group and not knowledge area
Prepcast has the best questions quality compare to what other providers " and really close to the real exam"
Spend more time and learning quizzes rather than mock exam, because as you go as you learn

Books: PMBOK only
Aileen website self learning videos + Pmprepcast bank questions
