Hello all,  I am planning to take my exam in about 2 weeks.

Now, i know that no two tests are the same , but from your experience what topic is most covered on the exam?
I have heard from a few people that by far the most common topic they encountered were streams.
Most of my practice in my own time has been with streams, generics, and concurrency.
I am asking because there are 1 or two topics that i dont get at all such as the fork/join framework.
If i am only to get 1 or 2 questions on this topic, then i wont even bother to learn it thoroughly as it will take me many days to fully understand it.
Imo its not worth the effort putting so much time into one small topic where i could be reviewing something else.

Also another questions even though it may seem kind of silly,
With covid-19 and all, and with the availability of taking the test from home now, is there anychance the test may be harder at home than taken at a testing center?
idk just a weird thought i had, im assuming you must have a camera, mic, etc but from my pov i just thought with the possibly of a candidate cheating they might give harder questions. lol.

Thanks again,
Sebastian

No. The supervision will be much tighter because of the opportunity for cheating at home, but the questions won't be different. You may need to strip the room you use for sitting the exam, and you may not be permitted to leave not even for the WC.

Yep, there are a lot of Stream/reduce/Collectors and Collection related questions, make sure you understand it well.

Other topics had around the same proportion.

Fork Join framework is not that complex, please read it through, no need to understand it in detail, the material in Sellikoff book is enough, there are some questions regarding thread, concurrency and probably 2 questions about Fork Join. Even 1 right question matters and can determine whether we pass the exam or not.

And shockingly there were some JDBC questions about update-able result set, please be prepared for that.
