I don't know if here is the right place to ask this question, so excuse me if it's not.
I want to take the SharePoint 2013 certification for developing applications (70-488)
I want know how much time it can take to learn SharePoint and prepare for the exam (I never worked with SharePoint , i'm just ASP.NET developer).
I know that it depends on how fast I learn, what you think for ordinary person ?
