If you are very strange to C# language ,and you have difficulties with C# part ,IN my opinion ,you can find some materials related with this part such as pratice exams or some training courses or C# books to help you study .
And if you have no problem with it ,and you can grasp it well ,you can jump straight into learning the 70-536 material .
hope it useful for u.
