Youtube videos with great study info

I created a youtube page where I post informative videos for guys and ladies who are preparing for the national exams.?ÿ The videos cover a lot of different topics and could be found useful by experienced surveyors as well.?ÿ I recently became licensed and I know what it is like trying to find information for the exams that you don't have to spend hundreds of dollars on.?ÿ I'm just doing these videos to help the profession grow and to clarify some of the difficult surveying subjects.?ÿ?ÿ
