Tons of things to learn but the videos make it simple

The instructor keeps it as interesting as possible.

Nice overview of the Z platform. Excellent trainer!

Not all the topics given in the quiz were covered

it is very much fast and not so effective

This was an excellent eye opening course

Buena información de los MAINFRAME

Explanation from Jeff was Best.

a good explained, very nice.

Good info. A little slow.

Good course and helpful

Nice course

Love it

This course has some serious flaws. It's supposed to be an introductory course, but no beginner can reasonably follow the content in the manner that it is delivered. You'll get a video on a really simple topic like "What is an Operationg System?" and then immediately get hammered with massive amounts of technical vocabulary that is defined only by referencing other technical jargon. It gets tossed out so fast that there's no serious time to assimilate any of it. Even if you rewatch videos over and over, it's almost impossible to follow all of it. This is a classic example of what happens when experts forget what it is like to be a beginner learning the material.

I really think the big issue is that the course isn't long enough. They should double the length of the course and just go slower. The guy making the videos is passionate. We could use more of him, but he needs to slow down. Every topic deserves its own video. The material should be explained with as little jargon as possible. They need to get a test audience of non-experts to try to follow it. If they can't, rework things until it goes better.

At the moment, I don't get who this course is for. It's an introduction to a topic that is only comprehensible if you are already an expert. The quizzes are really hard and I don't think watching the videos prepares you for them. You can pass them by reading through IBM documentation (hundreds of pages of which are linked in the course), but then why take the course? The course could be structured in such a better way...

Far too much material on systems programming, but with no mention of JCL, etc. Far, far too many questions not discussed in the presented material, requiring logical guesses, no matter how many notes you took. I can see why this course was added to the M/F Dev program, as a high-level technical overview of mainframes, but important topics, like encryption were glossed over in favor of systems programming sample code. The whole course *required* that admin experience in another platform, like Linux servers, be required to even have a chance to understand the material. This course needed to be more graphical, more visual, with more basic diagrams, and actually be for beginners. I can't imagine attempting this material without over 12 years of Linux experience, plus experience in Python, C, VB, and SQL.

There is a inconsistent level of detail: high-level overviews followed by deep dives into topics that are not clearly explained why.

Dry, very dry and alot of acronyms to take on initially. Could be convayed better.

Without seeing the hardware, it's hard to follow you.

Marketing and vendor exercise, nothing else for now.

The teacher seems personable, but there are SO MANY topics covered and things mentioned that if you have no exposure to a mainframe, you will be lost. A lot of the quiz questions are not covered in the lectures. I am hoping the rest of this path is spelled out a bit better...since I was not needing any experience before this.

Very dense—heavy on acronyms, light on concepts or frameworks/mental models. They could have presented this material so much more effectively. :(
