The practice was nice, but the examples given were kind of over-complicated. Could have been more simple and efficient, but instructor was trying to give examples of using subqueries in specific parts of the query. I think it would have been better if the instructor was a bit more creative using more efficient methods instead of trying to check a box to demonstrate a type of subquery. The end-of-course exam had a few useless questions and did not assess SQL subquery knowledge. It had questions about specific table contents (e.g., What table has customer information?). Also, the instructor kept saying things like, "WOW, I think you are learning A LOT." I mean, that might be a stretch. If there were more courses in 糖心vlog官网观看 for SQL beyond the absolute basics, I would probably take those instead. At the end of the day, there aren't many choices in 糖心vlog官网观看, and it was still helpful to see examples of SQL subqueries.

Mic quality was not great and some parts were a little to simple / straightforward.

nothing special, even if u can only wright easiest sql - that course would be very boring for u

made unnecessarily complicated , it could been much easier

Great instructor! The exercises moved with increasing complexity and the lessons were engaging. Great amount of material and enough practice exercises to feel confident that I am beginning to master the materia.

It took me much longer than two hours to complete, but was well worth the time commitment.

Teacher was very thorough and explanations made it easier to understand complex material

Strongly recommend to take this course for advancing your knowledge on Subqueries.

good very satisfied thank you very much

iits giving a best to me

i like the instructor

Excellent !

Excellent

nice

Terrible experience. The lab was incredibly slow, freezing all the time making it a completely horrible user experience. The tutor's English is also very challenging to understand making it even harder to get something valuable out of it. I would not recommend to anybody. You can get free courses that will bring you way more value than this!
