Hi guys, the last Monday I passed the 1Z0-817 upgrade exam with 93%. I studied using the following materials (about 3 months of preparation):
This forum of course Java 11 Upgrade Learning Subscription (Good value for money, Offers a good overview about JPMS and the new features plus exam voucher)The Nicolai Parlog's Book Part 1 The Java Module SystemThe Mikalai Zaikin's Upgrade Guide (A nice review about all the topics)Enthuware Mocks (Good quality mocks) I first sight I found the Enthuware mocks are a little bit more difficult than the real test.
The topics I found more difficult were related to Streams operations (findAny, findFirst, allMatch, noneMatch, groupingBy, partitioningBy), this because we need to process all the operations in our head, but It's ok at the end.
I took the exam with the OnVue online proctoring and I think It was a good experience and excellent alternative vs the traditional one.
I'm very happy with the results and I'm reading about the next one.
