If you have the time, practice the hands-on exercises that are provided with your exam preparation material. Log into your Exam Prep Software every day. Answer every homework question, follow the instructions for each exercise, and do each example exercise. Do all of your homework questions before you begin the hands-on training exercises. After you have completed all of your hands-on training exercises, take a post-deployment exam to verify whether, or not you understood what you learned in step 1. Test yourself daily by doing additional research on topics that are not included in your certification preparation material or that are still unclear to you.
