When are we getting upgrade on SQL course?

Question

An upgrade for learners that are done with the fundamentals.

Answer 1

Hello Abiola. As this is a community driven Q&A area, you can expect to get an answer from other learners. However, your question can only be answered by the technical support/dev-team and not by learners. Maybe you want to file some request at a more appropriate place.
Anyway. There are many articles that teach further SQL after the fundamentals. Check them out!
Also, challenges may include questions that point you on more advanced topics you may then ask the search engine for.
I also agree that all the certified courses should be upgraded to cover more content and be tougher to solve, but I honestly do not expect them to change drastically in the near future.
In that sense, happy coding!
