SOP

No, it is not a good idea to use same generic SOP for all the universities you are applying to. It is important to customize the SOP as per the university. You must check any specific SOP guidelines provided by the university. These guidelines may include particular question, instructions or even SOP word limit. Incase, no guidelines are provided by the university, you must prepare the SOP as per the university course and requirements. An SOP, which includes 
specific details about the university resources, facilities, and impressive features, and how they align with your goals, is certainly more impressive than a generic SOP. You can even gain an edge when university finds that you are serious enough to research about the university and its offerings. Aligning your SOP with the core values, mission and vision of the university can also earn you brownie points when comes to selection process.
