3 weeks of devoted efforts are enough, though you may start penning down your essay thoughts and structures even earlier. 1st part that you have to address is the content, i.e. the goals and achievements. Once that detailing is done in a readable Situation-Action-Result format then writing up essays is not far. It's 80% thinking and 20% writing I believe.
My current plan for my GMAT and Round 1 application (Nov 20th deadline) leaves me only 3 weeks between finishing my GMAT and finishing my essays to apply in Round 1. My preference is to definitely get everything done on time and apply in Round 1.
Question: Are three weeks enough to write essays to the Haas EWMBA program? Is there any advantage to applying in Round 1 vs Round 2?
