  1. Declan Canavan

    This was hands down the BEST course I could had enrolled for to help me prepare for the 1Z0-819 Exam. The questions in these practice exams were very similar, if not almost identical, to the questions on the actual 1Z0-819 Exam. Definitely would recommend you enroll in this course as the last step to your study plan if you plan on taking the 1Z0-819 Exam!

  2. Diptanu Sarkar

    I tried this certification once earlier and missed by few points… Then I went through these practice questions from skillcertpro and today I cleared the exam with good marks. Surprisingly the questions I got in the exam are completely out of these 15 practice sets. I would strongly suggest everyone to definitely practice these test irrespective of what other study materials you are reading. This will help you to clear the exam for sure.

  3. Bogdan Furtuna

    I cleared my 1z0–819 exam this morning.I was studying the exam course through other books which to be honest was taking away my interest for this exam.I was recommended by my friend to try this course. So I bought this course and gave multiple times each test till I got a score of above 95%

    This course is seriously worth each penny I spent. Most of the questions came from this course. Also, just a tip make sure you read the incorrect answers as well with the explanation. Also keep practicing till you get above 90% score (I know this is time consuming, but trust me this works). This course will definitely help you in clearing this certification.

    Highly recommended!!!

    Glad I took these practice exams! The questions were helpful to see and try out. The explanations for the incorrect exam questions was very nice as there is a little description as to reason behind what was actually the correct answer! Passed!
