1) Their simulator has some errata. One of the questions about MDB calls a method that is not available in it's superclass or own class. The question then states options of different errors out of which one was a compile error. This is clearly what will happen before the deployment error that they think is correct due to the MDB using another MDB as it's parent.
2) One of my questions had a duplicate answer that was the same option. I chose one of them but got it wrong and below the same answer(duplicate) was marked as the right answer!
3) More seriously I purchased an exam voucher from them and was having issues using it. I then went to their live chat option and had the CSR ask me for my prometric log in details! I don't that this is desired and I have serious doubt about giving any log in details anywhere to anyone especially when it is not even a site that is under their control. So be aware and be informed about their simulator.
