I have attended the sql certified expert beta exam this morning. There were a lot of errors in it, I added in the comment that they have to groundly review their regular expressions questions. There were a lot of rubbish question, but hardly any challenge, it is more like detecting the incorrect syntax. So I am deceived. I have to wait 3 months for the result, but I expect no more than 90%
They even have an exhibit with a table containing many columns with the same name (!)
Well, I hope they will improve with the comments I made when the production release will come out.
The time to answer the question is sufficient. I had only 139 questions in 3 hours, and I needed only 2 hours actually with plenty of time to review.
