I am seriously disappointed with the quality of the EPractize Labs's Web Services Training Lab. IMHO, this software should not be mentioned in the links for this exam because it is just not worth it. Proof follows.
Firstly, the lab interface seems to be designed by a 2 year old. When you're practising a session, there's no way of going back to a previous question and changing the answer. There's also no way to verify your answers all at once when you're done. You need to click a stupid button called "Check Answer" for EACH question which, supposedly, shows the correct answer (see more on this later) and then you'd have to click "Next" to go to the next question.
There's no way to suspend the session. You either finish the practice session or you quit, in which case you fail.
Quality of questions is below average. Most questions are so poorly written that they give away the answer. That is, if you even understood the question to start with.
The question bank hasn't been updated since Aug 23, 2011. Clearly, they hurriedly released a Beta quality software to make money when no one else was providing the same training and then forgot about it.
Many questions are completely off syllabus. I've not taken screenshots but if someone is interested, I can attach some.
[list]For many questions, the software would mark your answer wrong even if your answer is the one they call correct. How ridiculous is that? See attachment for proof.[/list
Yes a sarkar is right, this product is not worth. There are several mistakes with this, I feel fooled.
Unfortunately there is no training material for this certification, the EPractize lab can make money.
It's better to pay for the Martin Kalin material, even though I haven't seen it.
