This course has really helped with optimizing queries that I work with everyday, enhancing my understanding of RDBMS, joins, analyzing and structuring exactly what you need and yielding those results.

I thought this course was great! Great introduction to Relational Databases and SQLite. Highly reccomend for anyone new to SQL, Databases, or someone looking to get started with a data science career.

I think some parts are not explained well and lack of examples, furthermore complicated topic are treated fast and easy topic are treated in a deeper way. I found myself in difficulties and there isn't a way to ask a mentor more infos about the topic.

This course can give you knowledge of basics of sql queries (at least I got), but there not enough examples of how they work and practice, not enough ability to write queries on your own, sometimes not very clear explanation or mistakes in examples.

This is a basic SQL course. I'm not sure why it is called "SQL for Data Science" other than that is a catchy title. I took this course to refresh my SQL skills. It did give me an idea of where I am weak, but I don't feel I achieved my objective.

El curso fue muy básico.
En mi opinión hubiera sido mejor si los contenidos de las semanas 3 y 4 fueran más prácticos.
Las preguntas del examen final tenían una redacción muy pobre y ambigua, y no había mentores encargados de solucionar dudas.

After the 2nd week, the instructor just introduces new concepts and does not explain the working of the algorithm. Also, more or less the video length should increase and more examples should be discussed.
Overall the course is great !!!!

The biggest issue is the lack of practice . They try to stack on lot of things and ask a quiz at end of a week which is the only mean of practice. Coding doesn't word that way atleast could have given some practice after every lesson.

Quizzes and assignments require a lot of knowledge not actually covered in the course forcing you to search for information elsewhere.
Questions are not clear in many tests creating incorrect answers which are not of the learners fault.

The course teaches good information but many of the quizzes involve information that was barely (or not at all) covered in the lessons. It would help if they fixed this or were at least more active in the forums to answer questions.

The course is not bad but, and this is a big but at least for me, they do not provide DBMS to practice with and no practicing material. Also, some of the links provided to get more info about different topics is way outdated.

The quizzes and readings were helpful. The lectures were helpful for some problems and for some they were just too long without containing multiple examples. The peer review assignment was the hardest out of the whole course.

This course is okay but I feel like they need more practice queries not just a test and you never got to try it before also the questions need to be better explained. Other than that I feel like I did learn the basics of SQL

I learned some basics about SQL and enjoyed it, but I think there wasn't enough practical instruction about how the code is used. It made it hard for me to figure out how to get the data I was asked for in the assessments.

This course gave a really strong overview but some of the questions in the assignments were ambiguous/needed clarification. From the discussion boards this has been the case for quite a few years without being addressed!

The course vidoes were really nice.
The wording of the exercises is frequently confusing, especially in the peer-reviewed assignment. Many question cannot be answered with the tools provided (i.e. inference, correlation).

THERE IS BUG IN YOUR PEER ASSIGNMENT SUBMISSION THAT THERE IS NO "SHARE LINK" OPTION GIVEN AND IN YOU HAVENT MENTIONED ANY WAY TO DEAL WITH THIS PROBLEM. IT IS REALLY FRUSTATING AND THIS PROBLEM SHOULD BE RESOLVED.

Course materials are good, but wish they provide the actual SQL code in answers to quizzes and assignments. Simply providing whether my answer is correct or not is not enough for me to know what I did wrong.

course was really good and understandable for some beginner like me but at same time I think that more coding exercises were required
ONCE AGAIN THANK YOU FOR IGNITING THE INTEREST TOWARDS DATA ANALYSIS IN ME

The general structure and idea of the course was good; however, there were many times when the script/questions were worded badly and this was sometimes an issue when it came to understanding the content.

No practice examples at all. Videos have only theorethical queries without results, so you can`t see how it works on practice. Reference to SteckOverFlow is awesome. Why should I pay money for nothing?

Would definitely need to watch Youtube videos to understand the course fully.
Good assignments but the videos are not that great and too much time wasted in learning objectives. Too less examples given

Good program for beginners. Peer review assignment needs to be updated. The assignment is not graded by instructor. Certification means nothing because anyone who pays money will eventually get it.

There's a significant amount of hand-holding right up until the final exam which then requires a superior cognitive leap to overcome the far-beyond-beginner questions and reasoning. Caveat Emptor!

Overall, it's a great course to be introduced to SQL without any background knowledge. However, lectures in Week 3 is hard to understand, which I need to seek for other sources to learn on my own.

The course gives us the basics of SQL only wrt Data Science. It does not tell us much about SQL. Would have liked if more information was given on SQL and how that works. All in all, good course.

Certain quiz questions were unclear. Final peer-review assignment had unclear/ambiguous questions that didn't fit with the data in my opinion. But content is useful. Delivery could be improved.
