I loved the whole experience beginning to end. I came in already having a BA from state university. Well organized, well produced, and combined with note-taking this course is a no-brainer. Go for it!

A very comprehensive look at IT Security. I've learned everything from encryption and decryption to whitelisting, and how it pertains to real-world scenarios. Very useful to learn when it comes to IT.

Hi, This is the same issue from over 6 months until now not solve so please solve it as soon as possible. When I'm in the "Partitioning and Formatting a Disk Drive in Linux" Lab I pushed "Start Lab" button I get this message: Sorry, your quota has been exceeded for this lab. I asked for help from the Help center but I got worthless help so I tried again and again and this is what I got after all: {"status":500,"error":"Internal Server Error"} So now What should I do?

My review is the course isn't finished and Coursera isn't up to the task of hosting. I paid to be a beta tester.

A good bit of the labs didn't work and I can't even retake the last exam to finish the course. Coursera's support staff has assured me an engineering team will be looking into the issue eventually.

Is there good information in it? Yes. But could I do it over, I would do a slurry of CompTIA certs instead.

Course contents are not bad. However, it is not easy to get certificate due to technical glitches in Coursera. In addition, there is no direct contact to share our problem and there is no resolution.

Why students have to suffer? I am not satisfied with services provided by Coursera. If I would have a option to give zero star, I must given zero sar but cursur doen not allow me to do this.

It is just a primer. This will get you a job in the chat-box helping people perhaps. Very unhappy worst $40 I ever spent. I have had zero job responses even from employers since taking this course. If Coursera can find me a job in this field granted the chat-box is all it qualifies you for then I will re-write this review.

The course severely lacks visual aids and it is delivered in a robotic fashion that is not inspiring nor clear. At times the course felt like learning "vague security concepts" from an audio book. This is not how IT courses should be presented or narrated. The course format needs to be revised from the ground up.

Finished all courses, did not recieve credly badge. Big waste of my money. I paid for this course because I needed the ACE credits. Now I still need to pay for a college class as well. Lazy on the part of the course administrators.

This is the worst course I have taken on your website so far. A ton of information and different terms being thrown at me very quickly without going into any real detail. I feel I have learned nothing.

WHY my Cert is "Google IT Support", NOT "Google IT Support Professional Certificate"?

This chapter many thing is not must to know. All the course is Wide and Deep.
