Actually I didn't finish my Analysis of Issue (2nd essay) the first time around, because I didn't put any thought into it prior to GMAT, and I was stumped during the heat of the moment. I was mentally prepared on how I was going to handle the Analysis of Issue essay for my 2nd retake.
My approach for the first essay was straight forward, I just attack the crap out of the argument. I used the standard 5 paragraph approach, introduction, then attacking 3 different assumptions that the argument failed to address or clarify, and end with the two sentences conclusion.
My approach for the 2nd essay was also straight forward, pick a side and cite examples as support. Initially I was going to make 4 different arguments, but I was running a bit short on time so I presented 3 arguments instead. I was a liberal art major, so I was able to provide a lot of examples with historical context as supporting premises. I think the key for the 2nd essay is to have lengthy supporting evidences, and also be able to connect them to the main point.
