A great way to wrap up October—especially on a Friday!
It took some time to get the results. The OU servers must have been pretty busy with everyone rushing to finish the certification race on the last day!

OCI 2025 certs: renewed and done ✅
Time for the Oracle Database 23ai OCP—because who needs free time anyway? :)

For me, this is the toughest OCI certification.
Maybe it’s because I’m not a "networking" person, but I still feel the questions are much more difficult than other OCI certifications.
This time, I cleared it in two attempts. Last time (2023), it took three.

If you enjoy low-code development and have some free time, check out this free Oracle APEX certification—it's available at no cost until May 15.
I tried it last night, and the exam is very well designed!

This year, I finished them early!
Completed all three hands-on OCI exams.
Surprisingly, I scored 100% on the Security exam — totally unexpected, especially since I spent the first hour thinking I was going to fail!

If you have some free time, I recommend trying the three new 2025 OCI Foundation certifications. They are free and can be completed quickly.

This one was hard!
I've been taking this exam since 2019, and there’s one question that appears every time. I still take a lot of time to figure out the answer.
