GSOM simulated question bank is not an expense I must say that. It is a kind of investment that helps bag a bigger pay package in the future. GIAC Security Operations Manager exam was cleared by me recently on the basis of these mocks. The topic weights, passing score, exam duration and even the question format is very similar to the actual exam. The environment is strictly maintained as to the real. Questions have been asked from every topic in the syllabus so my entire syllabus got covered easily. I will highly suggest that mocks are a must before the actual examination as it helps cover the syllabus and the mental state.
