LSE marketing masters

Im going into my final year and am thinking about applying for LSE marketing masters course.

I'm quite unsure of how to make my application strong and stand out. for my second year i got a 2:1.
Im hoping my GMAT score will add weight, and completeing and achieve google certifcates for project management and such.
Im also doing a certified havard business course right now which will give me a certificate at the end.

How else can i improve my application? Or is applying quite unrealistic?
Im also thinking of applying for Imperial's innovation, entrepreneurship and management course because it seems more niche and less competitive so i could have a higher chance at getting a place?

The main thing im worried about is that compared to other applicatns i do not have any work experience pretty much.

Please help / please be blunt lol
