simplified I can grasp the info.

By Rashid Amir Williams on 9/3/2020

The course is really informative, the instructor speaks clearly, and I am understanding the concepts really well.

By Wingamang Chawang on 8/23/2020

Basics. But God Mode was useful though..Loved it.

By Carmen Davis on 8/11/2020

The information is really good and well presented. The entire problem is that it is out-dated. This is NOT FOR WINDOWS 10! Because I've been working with Windows since it first came out, I was able to glean a lot of helpful information but it took more time because so many things have changed such as MY COMPUTER which is not called that anymore. I come into contact with people who use older versions of Windows and I know this would be applicable to them but the correct versions it applies to need to be in the course description! The instructor used good analogies to help understand the why of things.

Very excellent course recommend it for every windows user

By Stephen Green on 6/2/2020

Everything is well explained by the tutor using visual analogies to compare with something that is more understandable and easier to relate with.

I never want to rate a course too low, but really disappointed, it's too basic, and definitely not worth with the price, it should be a free course.

Great teacher and great way of teaching!

By Weslee Hoole on 2/13/2020

I found the pace a bit slower than I expected. The rocket science section I feel saved this specific course. and it was in this section i felt the most intrigued.

By Miguel Williams on 2/7/2020

was all great

By Seth Mickles-Vickers on 7/23/2019

Found some tricks, would recomend it myself to people without know how of basic computering, some I have known and some I have not despite my history with computers. Though it should be updated for Windows 10.

By Ed Santos on 2/5/2019

Very useful information, not obvious stuff. Presenter went at a good pace and was easy to understand, engaging.
