I am new to IT, and was offered a once in a lifetime shot working as a desktop support tech for the Department of Defense. In accordance to the new mandates, DOD employees have to possess a Sec + cert. I tried so many other methods, until one day stumbled across your videos. The rest is history! The videos of course are wonderful, but what helped me retain this information was the hard copy of the notes I purchased from you. I was able to use that as a guide, and mark off things I knew, and work harder on those that I didn't know well enough.
