I passed CKAD exam!
After weeks of preparing, I finally passed the CKAD exam. CKAD consists of 16-20 hands-on tasks. I’ve read that time management is the most important thing on this exam. I have to agree with that.

Of course, I’ve heard that the real exam is a little easier than killer.sh. But it didn’t convince me. I decided not to study more, and instead decided to manage my time better.
