Way ahead to the age-old practice system

So when my uncle appeared for the Net Zero Cloud certification exam, he had opted for the PDF sample questions. When he heard that I have opted for the Salesforce Net Zero Cloud Accredited Professional premium practice question bank online, he was amazed. I made him understand that the mocks are online and even assessment feature exists along with a list of correct answers with mock questions. All this was pretty new to him. he was very sure that I will be able to clear the exam.
