Oracle’s Java Certification has a tough passing percentage, close to 65% for both OCAJP (The Oracle Certified Associate Java Programmer) and OCPJP (The Oracle Certified Professional Java Programmer).

You need in-depth knowledge of Java Programming language and API to succeed in the exam.

Also, the preparation for OCPJP is not very different from OCAJP, though you have to use resources that are focused only on OCPJP. You also need to cover more topics and in-depth because OCPJP 8 is certainly a tough nut to crack.
