I learned a lot, like I have some ideas at what the issues were during course 4 when the tests kept timing out and pumping out "You got this wrong".. when it was right..

It was the backup to that. It wasn't there. I spent some time constantly failing when it wasn't my fault. That hit my spirit HARD.. It took me longer to take this course because I was scared to move forward and hit that road block again. No one responded back to what could have been done, what was done, or will be done.. nothing was ever done or communicated,

So I continued and finished, by my estimations two months behind... and I did pay for that.

More hands on learning should be incorporated in to the courses. Providing a better skill and knowledge base for learning.

Better than module 5

Of all the courses, this was honestly the best one. However, most courses are filled with mistakes and errors, the modules don't work well, the information is outdated, and annoying jokes and liberal politics are forced on the student. This course should in no way be labelled as preparation for the CompTIA A+ exam. In information and conciseness, this course is far worse than Professor Messer's free YouTube series. The only thing this is good for really is the badge and credential, though I'm still not sure how much benefit this provides.

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.

You think that you'll have the certificate after completion? WRONG. Just try to use 7/24 Customer Services Coursera of ''NONSENSE'' for ID verification. Believe me, this company does not care about it's reputation but the fee of 50$
