While you can perhaps create an essay containing the identical approach for 
your school, the chances are unlikely you will probably have a robust essay without having weaknesses 
with no professional to check it over.  Pointing out the reason why you don't qualify for 
the position - Why do you highlight the reason why a company 
would not want to rent you, or the issues why somebody else 
might be a better recipient of that scholarship.
The good news is that you're going to also have allowed your 
head and subconscious mind to operate for the essay prompts when you weren't 
even mindful of it.
