The teaching value provided is great, and uses real life cases that I can relate to. 5/5 For that. However, it became a 3/5 stars due to the assignments not being as interactive that gives us an opportunity to write the code and have feedback from. Secondly, personal opinion, I definitely did not like there were a lot of limitations and constraints along the way to prevent myself to look in advance of the workload. Changing this would be beneficial to know what are the things to look out for during the videos.

It seems there was HUGE gap between this course and the previous one in the specialization. A lot of unaccounted for material and the difficulty jump is quite large. The structure of this course is subpar as there is no real learning; it's more or less giving you an exercise and then a VERY surface level explanation in a solutions video. However, the content is good. There is a LOT of material and it's all very useful - the exercises are almost all applicable to real world problems

This was a huge jump from the first course, I was lost for the majority of this section. I also don't like the way the lessons are taught. You just watch the instructor play around with the coding until she gets it and then you move on. You're asked to try to do it first before even knowing what exactly to do. And even when she explains it, you're still a bit confused. I did like how even she messes up and made it known that it's normal to mess up on small things.

The topic of this course is relevant if you want to dive into SQL and data science. But the course itself is problematic. Most tasks do not explain what is expected from you. I learned most through the solution videos, everything else was often simply guesswork. That is not how learning should occur! Also the rating criteria for the final assignment do not really align with the tasks. I would recommend Coursera to re-work this course substantially.

Topics and skills taught were relevant and good. However, more materials could have been given before letting us practise the practise questions ourselves. A lot of the questions needed knowledge of functions or ways of implementing SQL code that we did not learn before and it would have been helpful if this was taught to us first, rather having us learn from the solution videos.

La profesora es agradable. Las primeros módulos son la continuación del anterior curso, se aprenden algunos comandos más. Algunos ejercicios requieren comandos que no se han visto pero en los videos de solución los muestran. Recomiendo leer bien la página de ABBA (ellos te dan el link) para entender mejor en qué consiste el AB testing. Me gustó la plataforma de Mode Analytics.

The content of the course is very interesting, however it seems to me that it is not well structured, during the practices the objective in general is not understood, I think that the course should improve those details that not only consist of writing queries without knowing the meaning of each one of the variables that are being consulted in the different tables

I thought this class was a continuation of the first course, but realized there was really no continuity between the two. The instructor should have explained more in depth especially when using shortcuts in Mode Analytics. I did not always understood what was happening and needed extra help. This course could be fined tuned a bit more.

First week was hard to follow. I felt very discourage to continue that it took me almost a week to return and do the rest of the course. It got better the next weeks. However, I think that strategies and pedagogical teaching can be improved. What I really like is when Katrina coded on lectures, it was cool to see her thinking process.

The instructions were frequently not clear. I often took her literally, which was not correct. Sometimes she didn't specifically state something she expected us to do. Other times, she stated it differently than what she really meant. It was a struggle. But I'm glad I gained more knowledge and practice writing queries.

The data set used in course is incoherent. There was issues deciphering the tables, column names, field names etc. Instructions were ambiguous at times making it even more cumbersome to deal with the exercises given as part of the course. Answers to the questions given as part of the final project need a review.

The course structure is well designed to achieve the course objectives. I appreciate that the course addresses the real-world example and we can do practical exercises. However, exercise questions are not enough or well worded to understand what the instructor intends to ask. It could be a negative point.

It's a little bit disappointing that even when classes are recorded, Kat's mistakes haven't been edited and in a couple of times, in the middle of her struggling with some issue with Mode, the record were suddenly interrupted and next the issue was 'magically' fixed (would've been helpful to know how!).

Instructions need updating from initial launch. Instructions on how to create final report were missing. More instructions on developing codes would have been helpful. There was very little support and responses to questions posted on forum. More mentors would be helpful to assist with questions.

This course is nice, but there are many points that make tasks extremely frustrating: vague legend about an on-line shop, unclear tasks in the testing part, uncomfortable Mode Workspaces, which are obligatory to use, and no ER schemes (at the start you will have to guess which tables are connected).

The actual coding practice is a bit unstructured and not well explained. All the coding exercises could be easily skipped without even trying in the first place which is bad. This would be a great course if the coding practice were more strict with a definite code for a solution

This is a 3 star course as the concepts presented and the depth of the material covered was interesting. However, I am not sure that the way it was presented was optimal. More small and very focused exercises would have helped instead of large, sometimes hard to grasp exercices.

Some of the excercises are challenging but most of the times the instructions are not 100% clear. Also, despite statistics are not the core topic of the course, further explainations on ABTesting would be useful in order to make the process of answering meaningful.

Overall I've learned quite a bunch of SQL skills. I liked the applied character of this course. However, it was often not clear what to do. The teacher could have been more clear and precise. The first course of this specialization was way better.

It is an important course. However, the material of the course is not well explained. I struggled to understand what the instructor talked about. She speaks so fast and teaches inconsistently. It was boring and did not add much to me.

This was a very useful course. However, most of the videos lacked a context setting which made it a bit hard to follow. The slides could have been better too. But otherwise, the exercises were very helpful.

Suggestions for the Instructor - make a separate video on how to use Mode analytics it will help the learners that includes how to build a report, you can remove the lock features on solutions video

I don't think it's a good course.

To be honest, the content is very good. However the relation of different datasets is very very very ambiguous , it's difficult to finish the case study.

The class is hard to follow and the exercises are not well. But, we learn a lot during this class. I just think we could understand better if the exercices were better.

The practice examples are not written well- it is hard to understand what is actually being asked. This was also true for the final peer-reviewed example.
