I passed D427 in 2 days with no SQL experience.
I just wanted to give back to this community because the posts here helped me a lot.
I passed the course in just 2 days. If you already passed D426, don't stress too much about D427. Take the PA and practice it as many times as you can. The OA is very similar to the PA; they just change the data, and you also get a syntax cheat sheet that you can use if you forget the exact SQL syntax.
I also recommend spending extra time practicing the complex query questions. I missed both of the complex query questions on my OA, but I still passed as Competent.
Before the exam, I kept reviewing everything, but once I started, I told myself, "The worst that can happen is I have to retake it." That mindset really helped me stay calm.
Good luck with this course! I actually ended up enjoying it, even though some of the comments here had me pretty nervous at first. 😂
