Be physically ready. Rest before you test.
Your brain does not work as well under conditions of fatigue. Don’t go into an exam hungry or after a heavy meal. Neither condition will help your mental clarity and focus.

Get trained by Red Hat on Amrita Technologies.

The best way to prepare for a Red Hat certification exam is through the training offered by Red Hat. Just as Red Hat certification exams are all hands-on, Red Hat Training focuses heavily on learning through hands-on activities. We do not require people to take training in order to take our exams, but we strongly recommend that they take our training — even people who have considerable field experience in the area being tested. Your day-to-day work with technology will lead to depth in some areas and gaps in others. Training helps close those gaps and provides structure to your preparation.
