Threads and GC were tuff for me.
Even tho I think that I understand the concepts pretty well, the questions were tricky.
If you are scoring well with the master exams that comes with Bert & Kathy's book and if you understand all of the 2 minute drill stuff then
you should pass easy.
The mock exams in Marcus Green's book are also excellant.
Some of the questions are pretty tricky... most say that time is not a factor, but it was for me.... so keep moving... you have 2 mins per question and some of the questions take more than 2 mins to figure out what they are really asking for.
Again... Threads and Garbage Collection are probably what most folks have the most trouble with... but if you know the other stuff well, then you can
bone those and still pass the exam.
Drink
water... your brain functions better when properly hydrated!
After you ace the thing then keep the brain hydrated... but with more adult beverages
Good luck to yas!
