I took the complete Oracle SQL certification course on Udemy, got through the material no problem. The practice questions were fairly easy, and I also bought a few practice exams just to make sure I felt comfortable.
I just took the certification exam this morning and unfortunately failed, but the exam felt like a completely different world. Asking for tons of tiny details and advanced material never covered in the course or questions.
Is it supposed to be that tough? Any possibility they gave me the wrong exam? I'm not sure how to prepare for it when all the material designed to prepare for it seemed inadequate
Edit: exam was done online due to Covid. I asked them to verify the exam but they said they couldn't do that
Right? That's why I felt like I had the wrong exam, that one was probably in the middle in terms of difficulty. Thanks for the reference
I was afraid of that. Is there a good source to use to prepare? Because all the practice exams I found online were pretty trivial in comparison

I can write most of the basic queries just fine. It's all the fine points like, which of these are work:
SELECT "Hello we're home" FROM dual;
SELECT q'Hello we're home' FROM dual;
SELECT q'[Hello we're home]' FROM dual;
SELECT 'Hello we\'re home' ESCAPE '\' FROM dual;
Where I had never seen the quote operator in all my studying
