Very disappointed with this course. The class seems like a walk through rather than a platform to actually learn anything of value. It's terribly designed and overall lacks a professional touch (I feel like there is better YouTube content). The professor is hard to understand and seems to want to show off more than actually teach. Wish they would overhaul this course. The final is an absolute joke.

The course - Scalable Machine Learning on Big Data using Apache Spark has too complicated instructions for Labs. This course should be more properly organized like another part of IBM Professional Certificate, Intermediate Level - Machine Learning with Python. I don't understand why this course was included to this certificate. I'm not motivated to continue this course.

Complete waste of time. I would not recommend this course to anyone. I feel like I haven't learnt anything meaningful at all. Every concept has been poorly explained and frankly speaking, I don't see how this has helped me at all on my Data Science journey. This course is nothing more than a PR stunt to get more people to use IBM Watson Studio.

The course is a patchwork of incoherent and outdated videos, apparently mostly reused from other courses. Additionally most videos already contain retroactively added comments correcting, mistakes or outdated content. In my opinion it should be obvious that this course requires a complete makeover with updated videos.

This course could be much better. It is not as clear and explained as the first one "Machine learning with Python". It would be good to keep the same way of explaining. It should be "easy" to understand for someone who has never studied AI before (which is the case for the first course).

Compare with the other course in this professional certificate, this course didn't provide clear information to people want to learn. I spend very tough time on this course comparing to the other courses, I just recommend someone make a better spark course to replace this one.

The instructor breezed through course preparation and gave lectures from his car. Very easy course that doesn't challenge you or hold you to any standard of learning. One would be better off learning from YouTube and Apache Spark guides. Don't pay for this course!

Worst course i have ever took in Coursera. I would request IBM to replace this junk course from IBM AI specialization. This course doesnt teach BigData and neither teach Apache Spark. Too some extent it covers Machine Learning.

I had a bad moment passing this course because the instructor, He is jumping directly to the points without giving a proper introduction about the upcoming topics along with that he is explaining with bad English accent.

I am rather unsatisfied of the quality of this module. The pace is too fast and many things remain unclear even at the end of the class. Also I have found appalling that the trainer has broadcasted videos from his car.

very very superficial, there is no way anyone can learn apache spark. I feel like I have wasted so much time but not learnt anything at all. Really disappointing stuff from coursera

Poor delivery of course material, even worse video.

Instruction on quiz and assignments confusing.

You may get a bit hands-on experience of Spark but you LEARN nothing substantial.

Started nice with the first two "weeks". But week 3 and 4 are jokes with little to no content and final project is just running a pre-existing notebook and reading results

HEY, TO BE HONEST, I DID NOT LIKE THE TEACHER DUE TO MANY REASONS: 1. HIS VAGUE ACCENT, 2. HIS SPEED WHILE PRACTICINF CODE WAS HIGH AND STUDENT DO THE PRACTICE MEANTIME

The course is awful, avoid it. The instructor is evidently capable, but the course is just improvised, confusing, with lots of errors and not-updated material.

Very poor content quality, nothing to do with the quality of the first module.

new and complex concepts are assumed to be known from the get go.

Can`t believe this module was part of the course. very hard to follow. This course needs to be updated asap. what a waste of time.

This course is outdated, topics unclear, I had to jump to Udemy and Udacity to learn Spark.

Hope to see this course updated, Thanks

This guy should never teach any person at all.

The videos are very bad processed and the exercises are very bad documented.

I am really disapointed by this chapter!!!! I learnd nothing, week 2 evaluation is ridiculous I did it with Excel....

Low-quality videos, not relevant quiz questions. I can set up the same course in one day. Waste of time.

The quality of the instruction, video recording and scripts is ridiculously low! Avoid at all costs!

It was NOT a course where a CC was NOT required. I unenrolled and oprefer to learn by using Youtube

Hard to understrand teacher. Content of this course unfortunatly not enough for learning.
