In general the course was ok.The network explanation and the injection part of the course was very good. A good explanation and presenters which spoke clearly.

Although the course was informative, most of the training can be looked up online. I finished this course in 2 weeks and currently enrolled in cybersecurity boot-camp. These courses do give you methodologies and power points without structure. Like narrators sound like they don't want to do it, others can't understand (not because of language barrier) but more of a sound problem.
Yes, there's a bunch of information but what helped me the most was to watch the video, went to YouTube and watched other people teach the class and then researched the topics and take notes. Sure the badges are cool but this isn't a tech based course it's more book based but i will say that if you are planning on taking the Comptia Network or sec+ this course will touch up on the fundamentals.
Pros:
Informative class
Redundancy
very detailed
Cons:
Lack of support
Bad Sound Quality
repetitive information
No clear direction

This course is a good example that big names doesn't mean big quality.
I took this course from IBM expecting to see some highly skilled tutors & high quality teaching methods, but what I found were just power points presentation and voice quality that is so bad that you wouldn't understand a thing without the captions. which is a real shame cause the materials were actually good and useful.

The quality of content is inconsistent. Some chapters are executed in a clear and concise manner and seemingly had individuals that took the time to build out and review the content. Others are little more than copy paste thesauruses with nearly incoherent course structure. Frankly, the best portions are those taken directly from the IBM youtube channel.

It is a mix of webinars that have been cut and poorly edited to create a course. There is a part showing an IBM tool in a pre sales way instead of teaching the concepts.

Content is ok but the audio is really poor quality, most of the modules sound like someone is recording themselves on their 1998 Nokia cell phone ! really below par

1. the remote app to do course work takes forever to load and too clumsy. 2. the course overall is confusing. In the end I am confused by all the abbreviations. I got a more helpful summary from AI than the slides in this course. 3. better quiz questions are desperately needed because good questions can help organize thoughts and reinforce knowledge. 4. the assignments are not helpful. Just follow steps blindly. Not informative and don't add value. sorry for the review, but I had much better courses on coursera that were better organized and less wordy. At one point, I just wanted to finish the course and decided to learn this infomration in needed from another online sources.

worst garbage program I've taken yet all ai videos with broken lab environments that don't even contain what you need to do the labs; won't even let you type with your own keyboard. it's the bottom of the barrel when it comes to learning anything useful our cybersecurity certifications, wish I could have a refund.

De los cuatro cursos del certificado, el peor con diferencia... espero que los cuatro siguientes sean mejores. Hay algunas clases muy difíciles de seguir, los powerpoints poco elaborados y casi es inviable gestioanrlo. Gracias.
