I wrote a book for OCA which is
available in e-book form. There aren't a lot of differences between OCA 7 and OCA 8. I
mapped the objectives here.The main new topics are Java 8 dates and lambdas/predicates.

The main difference is that which exam you take for the OCA determines which one you take for the OCP. There's
lots of differences there. For people who want to take the OCP quickly, they should definitely take 7. You'd be ok with either. I'd recommend 8 because the OCP will focus more on lambdas and less on details of concurrency/threading/jdbc/etc that people don't use in real life. (They kept the most important parts on each topic.)
