I tried first time for this exam and after sitting in the exam i found out there are only 50% questions came from the wifi essential course and rest of the questions are about zD and product description etc. which i did not see in the videos of essential. Now my question is , do i have to finish my ZD 9.6 videos also to pass the exams or is there any other study material i have to go through.
Also if you could email me the receipt to my employer's firstname.lastname@example.org
would be great.
