Much like an actual project, it will be helpful to come up with a bit of a schedule for yourself. Book the exam for some point in the future and give yourself enough time to review. For instance, I gave myself 3 months to study and focused on the exam simulator, and Rita's Exam Prep Book. I knew what my goals were week to week as far as what material I wanted to get through, and ensured I left enough time for review.
Set your goal, make the plan to execute, make sure you have the preparation material, and go!
