Beware! Since not many people give detailed reviews, I will be that one. Today I finished this course. Here are some important things you should know before enrolling: Pros: 1. Covered most of the crucial aspects of data modeling. 2. Contents are consistent. Cons: 1. I found a lot of information redundant. Such as: 'Imagine you are a data analyst...' OR 'This could help AdventureWork to gain better insights on...' I mean, you say that once or twice it's okay, but you don't need to repeat information like that for each lecture. You need to work on your information granularity. Plus, tons of obvious typos and misleading phrases exist in the reading materials. 2. Lack of exercise examples. AND WAIT A SECOND, The TWO MOST important assignments were missing critical Excel files for download! And one of them happened to be the final project! Guess what, customer service won't help you nor refund you, they ask you to post this issue and wait for 10 days for a response. Excuse me, why are you wasting my time to compensate for your own mistakes? Hell, I know if you would ever respond to me since I realized ppl were reflecting on this issue months ago, and no one cares! 3. 50% of the quizzes were okay, as they were asking the crucial aspects regarding the important concepts, but some questions were just playing word teasers. I mean this is a section where students are supposed to understand how to use DAX to create measures and stuff, but the total number of questions about the DAX is very limited. Compared with the previous modules, this one is a big disappointment and failure. If after reading this you still want to enroll, my suggestion is to enable yourself to do more research and not solely rely on the materials provided within this module. Additionally, skip the unnecessary wordy content to save your time and money!

The content was really interesting, but most of the instructions for exercises did not match the content of the materials provided. Also, there were several problems loading graded assignments.

A bit sloppy, exercises linked to wrong input dataset, most of the video lectures repeat the same generic information over and over and do not really provide a solid foundation about the concepts

They teach like learners know everything and move so fast. Lack of examples in the lecture.

Most of it's good, but at certain times I feel like the course is trying to purposely gaslight you with how it words questions. Certain Jargon, and terminology is used that is never explained or never broken down enough for a layman to understand what they're talking about. I found it very challenging but I also learned a lot. I also had trouble with some of the exercises It seemed like I wasn't given the appropriate dataset to follow along.

Too many misconsistencies in study materials. Sometimes they forgot to provide materials. Sometimes they provide the wrong file. And everywhere there are typos and factual mistakes. Tests with SINGLE choice sometimes tell you to select ALL THAT APPLY.

terrible, videos with actors speaking lines they've learnt. No interaction for student in videos or links to practise files. Only 1 reading activity with a usable and practical practise virtual machine environment. Practise files with wrong data and reading activities with wrong instructions.

Multiple downloads were incomplete or just plain not the right ones for the lesson making it difficult or impossible to practice the skill sets covered. I wasn't a fan of how new concepts were introduced. A lot of information was thrown at you without a specific example to walk you through to apply and understand the concept until much later in the course. In general it was never clear how this information would help you build visualizations in Power BI.

Non matching files and examples are not explained properly. The learner has to already have the idea what should be done with data to understand the examples, as this is not explained with sufficient details. Most of the videos are full of corporate speak buzzwords instead of explaining how data moves with clear number and column changes.

Too many distracting typographical errors that require some proofreading, and one Activity made you download a file that was not matched to the exercise. It was simply the wrong file. Another exercise was describing a file that was supposed to be an xlsx file, but what was available to download was a pbix file. So much time lost figuring out why your results are not coming out correct, only to discover that you were given the wrong file.

This course can be structured in a better way and can be made easier to understand. Currently it is difficult to understand and takes much more time than mentioned. Some exercise files don't work properly.

needs some better explanation as we dont know everything and suddenly DAX comes and they expect us to know everything?

Do not recommend this course it cannot be done by our own pace, all the quizzes and practice questions are set to be taken every week, so it doesn't matter it you go faster or not, the questions in the forum section are never answered.

Very low quality control for this course. MANY hands on assignments where the data sets provided for download did not contain the necessary information to complete the task. There was also an exam where the "correct answer" was not the correct answer, as proven by the screen shot by the instructor. The problems with the course were reported as far back as 9/29/23, with no correction so far. And with Coursera's Help Desk only being able to help with problems with the videos, there is no recourse for the learner.

The content can be useful but a lot of the exercises were missing data, meaning they could not be completed. The exemplar images shown also sometimes did not match their descriptions, which is disappointing.

Difficult course a lot of issues with required files for assignments either missing or incorrect.

Lots of errors in this course.

Links are broken and course uses sessions which annoying for learners.

There are errors in the exercises (e.g. I need to calculate YTD measure on 'Total Sales' but 'Total Sales' column does not exist in the downloaded exercise file). The instructor is talking about trivialities (i.e. explaining the nothing in great detail) and when I need to use what I have learnt I have to consult the manual/language reference.

course failed to explain the logic behind writing DAX

Two things: 1. This course verbally discussed a topic, then jumped right to testing us on it as if we've already done it, then after that, showed us how to do it. That's backwards. Just watching somebody talk about something doesn't mean we know what we're doing. 2. On your exams, you make T/F questions the same weight as the tricky multiple answer (check box) questions. They're all 1 point. Now you know the T/F questions are way easier than the harder questions so why not make the ones that have 3 right answers worth 3 points. I think it sucks that I'm solid on say 2 of the 3, no question, but unsure of the 3rd. It's obviously a guess and you're going to give 0 when I was sure of 2/3 of it, and usually the one I'm not sure of is some weirdly worded tricky thing, maybe only mentioned once. It's something hard to remember, almost unnecessary or irrelevant, but you're give a zero for that. That's lame. Make every question meaningful. Don't screw people on these weirdo screwball questions that you know most people don't know. The ones who get it right are just guessing and luckier, not smarter or better.

This is more like a long series of promotional\commercial videos rather than practical tutorial. Instructed by different persons, the course lacks integrity and they go back and forth between different topics and repeat a lot of things multiple times. Some parts are tooo much basic and some parts are too advanced. A much shorter course in Udemy was much more helpful for me.

This course was very frustrating. Somebody needs to go back through it and revise all the missing or incorrect data. Update the materials to include correct or missing downloads. Add more information about the CALCULATE function. I found the information in Microsoft Learn area much more helpful than this course.

So many excessive words in videos. This course would be much better if tutors gave more examples. And it is pretty annoying when EVERY LESSON they describe what Adventure Works does, and that I am an analyst in that company

This course has good information, but the exercises are terrible. The data sets that are provided do not match the information given in the example. I am currently working on DAX relationships exercise where you need an order date and a ship date. The excel given to download is not the one depicted in the exercise and has no ship date.
