Reviews summary

Helpful for ibm mainframe developers

According to students, this course is largely positive because it's well received by learners who develop mainframe applications. Exercises come well designed and the lectures are clear and well paced. There are some issues, however. Sometimes exercises are given before the student has training and quizzes may have questions on material that hasn't been taught yet. Also, there's no way to ship progress and configurations to a new virtual machine (VM) when the current VM expires.
Lectures are clear and well paced.
"The course material and lectures are clear and well paced"
Course is helpful for mainframe developers.
"Recommended for all mainframe developers"
"Nice course, nice programming language"
Exercises help students.
"Exercises are well designed and extremely helpful"
"Going through exercises is the best way to learn"
Quizzes may reference untaught material.
"Quizzes have questions referencing items that have yet to be taught"
No way to ship VM progress.
"The VM environment that is provided for exercises expires in 2 weeks, all progress and configurations will be lost and there is no way to ship them to the new VM."
Exercises given before training.
"Exercises are issued where training has yet to be provided."
Exercises become out of sync with lessons.
"Also, the exercises become out of step with the lessons"
"The exercise link for a given week at that point is for material covered in the next week's course"
