I have successfully passed Exam 70-486: Developing ASP.NET MVC 4 Web Applications.
I used next sources for preparations:
- I went throw HTML5&CSS4 features when preparing the next short presentation. It was really helpful for me. I want to share one of the source that I used for my presentation - html5rocks. It is very useful slides that describes and shows HTML5/CSS4 features.
- ASP.NET MVC Advanced Topics: there are a lot of useful courses. I took one of them, but honestly I am not sure that it was the best for preparation.
- And finally my experience.
