I have recently schedule the exam for SCJP6 through Pearson VUE(1Z0-851). From books I have been study by Bert Bates,Kathy Sierra it writes that the exam duration is 180 minutes. On Pearson Vue page and in the Oracle official page it's writes 150 minutes. Why is this 30 minutes difference? Is anybody who has took the exam recently can tell me how much time is the exam?
