11 exam came out, I created a wiki page comparing the objectives to highlight what changed. This was helpful for those studying from a OCA 7 for the OCP 8 exam. However, the OCP 11 part 1 is a profressional level exam. It is harder and covers objectivies more deeply. Using an OCA 8 book to study won't work. This wiki page still shows the mapping of objectives at least.
Note: Oracle makes changes to the objectives. These Java 11 objectives are as of when the exam launched and may vary slightly from the latest. The gist is the same.
