Clearing the MySQL 8.0 exam was a big win for me, thanks to Pass4Success. There was a question on optimizing queries using indexes that I found challenging. I wasn't sure about the best practices for composite indexes, but I still passed.

I’m thrilled to have passed the Oracle MySQL 8.0 exam. The Pass4Success practice questions were spot-on. There was a question about the ACID properties of transactions that made me pause. I wasn't completely sure about the 'Isolation' property, but I still managed to pass.
