IT Infrastructure & Security - Winter 2020


(12/18) Points and feedback for projects from last semester are posted here. I'm always hoping for all As, but that only happens in the small sections over the summer. Please help bring up the As and reduce the Cs and lower. Cs in university are not 'average' grades, they are bad, you can't graduate with less than a B in your major... Bs are OK, As are greatly appreciated. Pay attention, TAKE NOTES, the subject matter for this class is dry but is essential stuff. Students who pay attention and take notes usually do well in this course. It is not a course that can be Aced without paying attention and taking notes...

Prior notes will be moved to Prior Notes when there are some to move...
