The course is quite dull and there are not enough visualizations of the system that instructor is talking about. The quizzes are not related to material talked about in videos at all and were quite difficult and out of context. Reading material was impossible to read - classic ibm 400 page document, incomprehensible to a beginner.

Basics could have been cleared out first properly, before going into detail regarding each component. Topics were discussed as if the learner had previous experience. This is not a beginner course at all!

for a introdutory course i guess the concepts are bad approch for one has not expirience with the IT.

Jeff is a great icon on this course. The weekly quiz however were really hard to solve for me. I have the feeling, that some questions are not topic in the videos.

Excelente curso pAra iniciantes, demonstra todas as particularidades do sistema z/OS e seus beneficios, de uma forma didática consegue entrar nas particularidades do sistema, demonstrando segurança, criptografia, recursos e features, softwares e particularidades de parametrização. Inclui material rico e permite interação com outros estudantes, um curso essencial para quem conhece e quer aprimorar ainda mais o conhecimento (autalizar) e para quem não teve ainda contato com o incrível MAINFRAME.Parabéns pelo conteúdo, apresentação e material do curso!!

Excellent course which provides an introduction to enterprise computing with IBM Z, presented in a very engaging manner by Jeff Bisti. Highly recommended for those who want to learn about mainframes.

AMAZING course covering IBM Z architecture, design, hardware and software components. Thanks Jeff and team for this very comprehensive overview of the platform.

Exceptional course. No doubt. God Bless IBM and Coursera for providing such a course for a such a good price. Very knowledgeable..... GOD Bless YOU ALWAYS....

The course was excellent, full of knowledge and Trainer Jeff was very interesting and making these an good course to start your career in Mainframe.

The speaker is top - explains well and makes funny jokes! The only reason why I give four instead of five stars is because sometimes the questions in the quiz were not covered during the videos . (pretty sure about that)

Pretty good information, hard to comprehend but that is to be expected. Best course I have seen for beginners learning about Mainframes

The Presenters were polished, knowledgeable, and well spoken, the production values high - it's IBM. But, much of the time the questions were unrelated to the content presented. Between having a good background knowledge of computing in general and having worked with mainframes long long ago I muddled through. There is plenty of good stuff in the presentations to have questions on.

The acronyms will have your head spinning. Quick heads-up. You will need to do a lot of reading on your own to better understand the underlying concepts.

I think it needs more coverage, especially for people who've never seen any IBM stuff before.

the is too much theory without any logical diagram explaining it.

Many terms not properly explained. I had to internet search to get test answers clearly not included in material. All delivered as though I was already an expert.

There are so much topics that aren't properly discussed during the course but appears anyways in the exams. NOT beginner friendly

This is not a course, just some guys reading slides. Better to read IBM Redbooks.

Très Bon cours sur le monde du Mainframe IBM. Le cous a l'air très facile au début de la formation mais très vite à partir de la deuxième semaine, des notions plus complexes et qui font appel a une expérience dans le domaine rentrent en jeu.

Je suis actuellement développeur dans le domaine de la monétique sur Host Z/OS, je trouve cette formation en accord avec les notions que je rencontre tous les jours dans mon emploi

This's a very informative and useful course. It needs time to learn all themes but explanations are very clear and understandable. Thanks a lot for IBM lectors. NB! Background experience (at least, theory) in system administration is strongly recommended. There's nothing extra hard to learn but I'm glad that I was not a total newbie on the beginning of this course.

I've taken an in-seat z/OS Boot Camp and read through all of the Red Books and I have not been able to understand nearly as much as what I've gleaned from this course. The topics are broken up into manageable chunks rather than the firehose technique. The quizzes are challenging but not impossible if you've been taking notes. Great course!

Short but insightful.

Jeff Bisti is a fantastic communicator and convincingly delivers on all the basics in a manner that will entice beginners without overwhelming them. This course is a beautiful consolidation and the only gripe I have is that it throws the learner into the second course without a proper preamble.

Though I have been using the Mainframes for 20+ years on different levels this course was great to know the internal architecture and different components of z/OS. You would not find anywhere outside videos how the z/OS built and different components in detail. I have now better idea on how it operates and IPL.

Excellent course! . . . The times of each presentation are adequate, the information is clear and updated. The support material is very practical and useful.And above all the instructors have extensive knowledge of the topics presented.Thank you for this wonderful opportunity to keep us updated.

Great course. The lecturer is presenting information with humor and is easy to understand. The material is well prepared and structured. Additional documentation is also well choosen from all the IBM docs. For me most interesting was mainframe architecture how the system is booted.
