Отзывы учащихся о курсе SQL for Data Science от партнера Калифорнийский университет в Девисе

The videos were not as informative as I would've liked them to be. When you input incorrect code there weren't many resources to find where your mistake was. It would be helpful to have a tutor or someone to chat with for help.

The course has no transcript for review. And the system of SQL exercise is also wrong when you are using “WHERE” Clause and “=” signal. Because of the mistakes of system I even can not make any progress. Please check.

The course went fine up until the final assignment. It was very irritating to do, because of the incomplete database, broken correlations, different tables stating different things, which should've been the same, etc.

bad experience on exercise:

In the course, you will learn different functions of sqlite but they merely bring you along with examples but pop out with tons of different exercises without giving you a single hint

The instructor spent too much time on unnecessary and self-explaining topics, and on the other hand failed to explain some important details. I ended up skipping much of the course and googled a lot by myself.

Decent introduction. I recommend https://mode.com/sql-tutorial for a better introduction to SQL.

Assignments are very badly designed. Also the questions in the final assignment are unnecessarily repetitive!

The lectures were not easy to comprehend for a computer language. Though the course mentions it is a beginner-level course, the lecturer jumps to a certain part where there is a learning curve expected.

A little too easy, not challenging at all, given this is a beginner level class, I'll give it two stars. You could finish the whole course on Saturday if you get up early plus Sunday if you do not.

Even reading the prompter throughout the course, the instructor has been extremely nervous and unsmooth in reading. This is the biggest downside of the course and eclipses its good sides.

I wish that the instructor used examples that mirrored the type of questions in the coding exams. We did not cover all the material in the coding exam.

The structure and guidance provided on the final assignment was very poor, resulting in far more time required to complete than expected.

too much theory, I needed something more 'pratical' that allowed me to start using and write code and not see a lot of slide with code

1.Very basic course.

2. Assignments level does not match with training level.

3. Need to provide class which includes query writing.

The teacher was not readily available to answer questions. The course was alright but I do not feel prepared to use my skills yet.

Very slow and badly organised start of the course with no to very little practice of how to use SQLite before the coding quiz.

The first exercises are still ok. But the final exam is really a mess. The questions are not as precise as they should be.

Too much talking in videos with less examples. The exercises were vague and not enough information was given to solve them

The videos had the wrong emphasis, and were far too long.

More time should have been devoted to the exercises/quizzes.

Not satisfied. There are better MOOCs for SQL/Data Science out there. I wouldn't recommend it for a SQL beginner.

G​reat information, however, the site that host the datebase for the quizes is outdated and no longer supported.

The course is good in itself, but answers circulate on the internet, making the certificate not very meaningful.

there is a lot of questions about how the questions were asked, i highly recommend you do see the discussions

Not enough examples were shared.

Certain concepts were explained without telling their underlying basics.

There are few examples about every lesson, and may not have examples for some lessons
