best NSE 4 mocks

I was very much scared how the exam environment will and this nervousness was not letting me cover the NSE 4 - FortiOS 7.2 syllabus as well. But after giving a round or two of mock tests, my fear started diminishing and when i gave the actual Fortinet NSE 4 - FortiOS 7.2 exam after many mock tests, i was not nervous at all.
