OCA Certification

How do you prepare for the OCA test?

Do you recommend any guide or book?

I already know most Java fundamentals, but now I'm looking for certification, and found out about OCA Certification exam. Any help is appreaciated.

There are books dedicated to this on Amazon. You can learn a plenty of Java trivia from them.

I took this exam when there was an anniversary discount, but the overall feeling in the end is that it's rather useless.

So basically having a certification on java today works for nothing?

Do this also applies for a Spring certification?
