Hi Friends, I read at several places that we should not memorize ITTO or its fine if we understand the process. Some said that we should remember ITTO as it will help us with few questions and with exam like PMP, every question will count ...... so I chose not to leave anything and started memorizing ITTO.It look me 3 months and still I may go wrong here and there. I mean I cant say that in all 47 processes I know each and every ITTO. I know most but may not know all.
