Yeah, it depends on how you want to approach it. If you look at the study guid, it’s divided in multiple sections such as
Storage Engine etc… So when you are done with a course on any specific topic then you can refer that section in study guide as well to see what you have learnt and what you haven’t. You can complement the missing knowledge by visiting documentation and other resources available on our website.
It totally depends on how much effort you are putting into it. Some people do it in months and some people take more time. Your performance in the
Practice exam should give you some idea if you ready for the certification exam or not.
