I failed this exam 2 times before. I found this site and got the practice questions hesitantly. But thankfully all worked at the end. I managed to pass with the help of theis stdy guide practice questions.
The Xenigne app makes studying more interesting as it provides an interactive way of answering and reviewing the practice questions. With 50% discount sale this is not bad of a deal.
Why is the problem not updated? There are 342 problems. The simulation or pdf has 300 problems.
One of the best exam preps I have ever used to pass a test. The test engine software is cool but there is room to improve. Over all very accurate and overs all exam topics.
Just passed my exam this morning after preparing for 2 weeks. I can breath now.
I downloaded the Xengine App, while it is free and good there is room for improvement. Please break the exams in to Topics/Sections. Randomize the answers under the Practice Exams Simulartor mode. Doing this will help with learning.
I just bought the exam prep two days before writing my exam. I studied the guide inside out and wrote the exam in under 45 minutes! The most amazing part is that I passed with a score of 1000!! WOW, you are the greatest and I will always use your products.
