Good question. The 1Z0-815 exam covers more material. In particular, it covers some topics that used to be on the OCP 8. It also covers some OCA 8 topics in more depth. Combined, this results in a good bit more difficultly.

I don't recommend taking the
Java 11 cert with a Java 8 book. If you have the OCA 8 book in your possession, I would recommend taking the OCA 8 test.
