Simulated exams are the best method to prepare

Hii..
I say this because i have been through the ordeal of not preparing at all in first attempt. I passed the second attempt for GIME through practice on mock tests. I found the mock tests for GIAC iOS and macOS Examiner certificate online. Prepared nicely, the maintained topic weights and passing score along with exam duration and also question format toughened me for the real deal.
