Comprehensive Acronym List

Postby didle » Wed Jan 21, 2009 5:07 pm

As a newbie, I admit I haven't visited all sections of the GMAT Forums and GMAT Wiki yet. But I see that the team makes extensive use of acronyms. Even for people's names. Edwin has me down as DI, but I prefer to be DI5 and that will probably happen eventually if I keep using it for myself!

Is there an easy place to find where we are maintaining a comprehensive acronym list or CAL? If not, I volunteer to build one, just tell me where to put it.

Hey DI5,

I'm only moderately less new than you are. I'm not sure that I've encountered an acronym list anywhere either. If you'll post the acronyms that you don't know as you come across them, then people can define them in a reply post. Then, we can compile the definitions into a more-or-less complete listing later on. I think this will be a good addition to the GMAT starter guide.

OK, I will do that. I have a request in to Steve Hughes to ask the GMAT team to send me their own acronym lists, and he thinks there my be an actual GMAT list somewhere. As the various lists get sent to me, I will blend them into one. Here is what I've come up with so far - (Note, I previewed the post and the white space was taken out so this list is much uglier than the original. I guess we need to add the functionality into our open source Bulletin Board service to preserve white space in the comments for better formatting capability. That's probably the subject of another post!)

GMAT is the test conduct to screen out the intelligent students from the crowd of the students to get the best students so far. Here you need to check my admissions essay review for the all level of students to complete their work. This forum is discuss the question related to thi test and to guide thes students about the preparation and teat.
