Cleared MCPD 70-576 exam / Prepartion material and links for 70-576

I sat for 70-576 – PRO: Designing and Developing Microsoft SharePoint 2010 Applications exam last Saturday and it went very well. I cleared the exam with good score. Though score was less than my last certification exam 70-573 I was happy to earn the score of 830 after spending lot of month for preparing myself for exam and getting the required confidence and Knowledge.

I discovered lot of SharePoint areas which were in dark for me before exam preparation. The amount of knowledge I gain is huge. Hoping that I will get chance to implemented all my learning in some of the projects I do then only it will stay with me forever and I will never forgot.

How I prepared for the exam?

There is no specific book which will cover all syllabus required for exam (even I don’t like reading book from start to end, I get lost in them). So the best way was to know the syllabus and learn all topics one by one with Google search.

While searching for the topic and learning I was gathering all the links in Excel for this blog post. Find below all relevant links for study:-
