Finally passed 1Z0-082 after two attempts — what actually worked for me

So I cleared the Oracle Database Administration I exam last week with a 78%, and honestly I need to share what changed between my first failed attempt and the second one because the difference was huge. First time I just read through the Oracle documentation and watched some YouTube videos. Big mistake. I failed with a 61% and had no idea where I went wrong.

What turned things around was finding a solid 1Z0 082 practice test and committing to it daily for about four weeks. I was doing 30-40 questions every morning before work. The practice exams I used actually explained WHY each answer was right or wrong, which is how I finally got the hang of the trickier topics like undo management, backup and recovery concepts, and the Oracle memory architecture. I also kept a handwritten study guide for areas I kept getting wrong — old school but it worked.

For anyone currently prepping, how long did you study? I clocked roughly 80 hours total across both attempts. Curious if that's typical or if I just needed to grind harder the first time around.
