Hi Project managers, I have recently got certified PMP though I was working as project manager from quit some time. The main challange to get certified is to find time to study as per the exam requirement. I found "PMP resource (Rise UP)" application on iphone/ipad very useful for studing and memorising key areas, ITTO and formulas. Glossary/Dictionary for PMP terminologies are very handy and clears concept immediately. I flash cards and exam sample questions gives you idea of your strong and weak areas.
