jongmin0919's honest review, Getting SQL Developer (SQLD) Certification Part 4 course

I'm really sorry to say this, but You're bringing in some incorrect past exam passages and answers and talking about them as if they were correct. I don't know if you're not aware of it or if you really think it's correct, and when you state the problem, your explanation of the problem and the passage is also very lacking. This person's theory is just for reference, and you should buy a separate workbook to look at the past exam passages...
