I am have prepared for the SCJP(Sun certified Java Programmer 6) and now I want to schedule the exam. Through the exam provider (Pearson VUE) 2 exams are listed with the same name but different code. Both are called Java Standard Edition 6 Programmer Certified Professional Exam and the 2 codes are 1Z0-851 and 1Z0-851-JPN. In the official oracle page only the (1Z0-851) is listed and is 150 minutes instead of 180 minutes???. What is the difference with the 1Z0-851-JPN examination. Which one should I to choose? Sorry if this question is very specific and can't be answer.
