I passed 1Z0-808 OCAJP SE 8 today LocalDate.of(2015, 07, 30)
with score 87%.
My preparation time was Period.ofDays(21)
My goal was to pass the exam with a score over 80% and fortunately I achieved it.
I studied OCA: Oracle Certified Associate Java SE 8 Programmer I Study Guide by Jeanne Boyarsky and Scott Selikoff
. It took me 14 days to get through and then I also studied Enthware mock exams
for about a week. Leitner mode was very helpful in my case.
It's considered a short period to get prepared for a certification but I studied long hours every day and I also relied on my existing experience as a OCPJP 6.
I decided to walk again the path of a new OCPJP candidate, and not take the upgrade, just to refresh my knowledge of Java fundamentals cause IDE has been my best friend in working environment for several years ;)
Good luck to you too guys!
