structure i used -> 12 times, 1.5 spacing, 1 inch margin, question at top, name in header.. that's my standard.
each has their own writing style clearly. my approach is this... im going to be successful with or without an mba. however i want an mba, let me tell you why i want an mba, and then explain briefly how your school is going to accent my candidacy and assist me in areas i have room to improve. to each their own... however i feel mentioning how 1 course or club is going to transform you into this incredible business individual who is going to take on the world.. that's foolish.. lets be serious. the mba is accenting an already successful applicant with a few skills/tools that may need further refinement or areas of learning to be ready for a new career or advancement in their existing career. my suggestion.. find one specific thing that the school has that accents your existing profile and leverage that. big ideas here would be bernstein leadership board and things like that.
again, approach it however you want and what you think is best. I simply think that if you waste so much space of your limited word count on specific courses and you aren't developing how these things are actually transforming you and highlighting why the mba is critical component.. you're failing to answer the question. the most important part of essay 1 is why are you pursuing an mba. why is this mba a necessity for your career. why now. how is columbia a good fit? you think a course is what makes it a good fit? i'd say it's not the course... it's the experience of nyc, alumni reach, educational pillars, cluster approach, diversity conferences, things like this... goodluck.
