Hi, so today I passed the IZO-808 exam with an 88%!!! I was expecting a much lower score going into the exam as my Enthuware test average was around a 76, but as a lot of people had already said the actual exam is MUCH easier than the Enthuware tests. I used an IDE (Eclipse) to prepare for the exam. I know that a lot of people said that people should stay away from them when studying for the OCA, but as you can see there was no harm done with using one. I feel like they save a lot more time as you can just press Run instead of doing javac/java every time, but I guess every person has their own way of studying. I really recommend buying the Enthuware tests as they were of great help and some questions were REALLY similar to the Enthuware ones. I also used the OCA Study Guide Jeanne Boyarsky and Scott Selikoff. I would really recommend this book to anyone as it explains every topic perfectly.
Good luck to future test-takers. Do not stress about it too much!
