Very good and useful practice of SQL. The JOIN party is pretty hardcore so I definitely couldn't master it but got enough of an understanding where I could learn quickly with some on the job training.

An excellent course for learning analysis techniques using Spreadsheets and SQL. Recommended for all engineering and data science students as well as for those managing businesses and human resource.

I had a lot of issues with this course. The instructor is fine and the quality of her videos is in line with all of the other courses. The course itself is structured very poorly. We went from very easy spreadsheet functions and basic SQL queries to much more advanced SQL stuff in Week 3. Week 3 was significantly harder than anything else. I passed the quiz, but I had no idea what was happening. Really complex queries were being typed out quickly on screen without any serious explanation of what was going on. I had to find other sources to really feel comfortable with JOINs and Subqueries. The Week 4 content was easier, and easily could have preceded the Week 3 stuff.
I find the quizzes are just annoying. There needs to be more questions on these quizzes. When you only have ~8 questions, you will fail if you get more than one question wrong. That might be fine, but there's always at least one question that I think is poorly designed. If you have multiple choice questions, there should be meaningful differences between the correct answer and the distractor options. If three of the options are things that would pass as correct in ordinary conversation, you are literally just splitting hairs over the answer that is technically correct. There is at least one of these really pedantic questions on every quiz. It's downright annoying because you can know the material well enough to explain how to do various things in Excel or SQL and then get these really nitpicky questions wrong. You'll always pass because you can just retake the quiz and do it again, but that wastes valuable time. If I'm going to fail a quiz and have to retake it, it should be because I genuinely don't know something and need a refresher, not because of a few poorly designed questions.
I also think the course fails to tell us very much about data analysis here. Five courses into the sequence and there hasn't been any sort of discussion of statistics apart from using functions to find averages. You don't need to get too heavy into math, but there should be some overviews of how to meaningfully infer things from your data.
The discussion boards are filled with frustrated people who have issues. Many of those posts have been up for months. The course could be so much better if it were just updated a bit. It needs more content. Give us more SQL examples.

This course has a lot to cover, but there were some major issues. First, there was a lot of repetition, especially when it came to spreadsheets. In the "Prepare," "Process," and "Analyze" sections, too much time was spent on spreadsheets, and concepts were repeated multiple times, which felt like a waste. It would have been more efficient if the course had just referenced the material covered in previous lessons instead of going over it in detail again. The same issue occurred with SQL. A lot of time was spent in the early parts of the course explaining basic syntax like SELECT, FROM, and WHERE. However, the real work began only from Module 3 in Course 5, where we delved into joins and subqueries. Unfortunately, the course didn't provide enough depth or explanation here. It also seemed to overlook the fact that some people might not have prior SQL knowledge. Thankfully, I had experience with SQL, which helped me finish the course, but if I didn鈥檛, I would have struggled and wasted time. When it came to subqueries, there was no clear explanation about the differences between using them in the FROM, SELECT, or WHERE clauses. The instructor just demonstrated the steps without explaining the underlying logic. The hands-on exercises were also poorly structured鈥攔ather than explaining the reasoning behind the tasks, we were just told what to write. Additionally, I noticed that some of the answers in the videos and exercises didn鈥檛 even match the questions being asked. In Module 4, it was just more repetition of spreadsheet and SQL content, which felt like a waste of time. The only truly useful part of this section was learning about pivot tables. Overall, I don鈥檛 feel this course offers enough depth in SQL to be fully educational.

2.5 stars This course kind of disappointed me. Up until now, I was able to keep up with all the concepts, but from now I always feel I need to stop and look for external resources to keep up with so much information. I don't feel the material and the exercises provided are enough. The instructor and the exercises took a lot of time repeating basic concepts from spreadsheets (such as Sum, Countif, Max, Min, Conditional Formating, etc), while more complex SQL subjects are briefly mentioned. The instructor seems more worried about spelling the FROM clause, than in explaining what the query means. Oh, and by the 5th course, I guess we all have understood what the * means after SELECT. No need to repeat it all over again. SQL queries became really complex all of a sudden, and Quicklabs are quite useless since they are copy-paste exercises. Plus, it's extremely annoying that some of the documents we are supposed to use are locked when we try to open them. It's manageable because you can download and upload them to Google Drive, but before you understand this trick, you just keep missing information and exercises. This is happening at least in the last 3 courses. I also think that some of the videos and readings were not in the right order (a theme appears briefly in a reading as something you are supposed to know yet, and then, after, you watch a video explaining that as it was the first time).

Bueno aqu铆 voy, primero el certificado es sumamente aburrido, es en extremo laaaargo, facil, pero tiene muuchos errores, a veces te imposibilitan para avanzar y obtener ptje m谩ximo. Me parece que de todos los cursos el 煤nico 煤til fue el de programaci贸n en R, quizas el proyecto final y uno de los obsequios por terminar el certificado, por eso le doy dos estrellas, no tiene sentido pagar por un certificado tan b谩sico y tan largo, creo que hay un teor铆a 煤til, que se puede explicar en dos semanas no en 15 semanas, ya que es solo formativa, se olvida al poco tiempo, prefiero un curso mucho mas practico y un poquito mas dif铆cil, le tenia mas fe, me siento defraudado por google al lanzar este certificado ,que siendo honesto, lo 煤nico 煤til para empezar a trabajar como analista realmente es el curso de R y Tableau, el cual este ultimo es reeefome y b谩sico, solo trabaja con tableau public, que pr谩cticamente solo se usa para compartir visualizaciones, en la realidad se usa tableau desktop, como m铆nimo. Espero que en una pr贸xima oportunidad saquen un certificado mas practico enfocado en la resoluci贸n de problemas reales y que si va a durar 8 meses que valga la pena y no le metan una teor铆a in煤til como relleno. Creo que este certificado podr铆a haberse terminado en 3 meses como m谩ximo, peero es tan fome y largo que les advierto, preparense para aburrirse durante 20 semanas.
