Gives Unlimited attempts to practice

I like the system of online preparation. It gives me the freedom to study at my own pace and at my own will. Edusum.com made it possible while i was preparing for Microsoft Power Platform Developer certification exam. The practice exams seemed so real because of features that the site has. One has to complete the exams in given time limit. However, there are unlimited attempts to practice and that’s great. The site is very helpful.
