I recently applied to HBS (and got dinged

), but I salute them for their amazing admission process. They don't require any official paper until you get admitted. It frees you from all the hassles/costs of sending your transcript/GMAT scores.
I found two other schools that also don't require any official papers until admitted: Olin (Washington University) and Cox (Southern Methodist University). Both are top 30 schools I believe.
I would like to list business schools the have the same admission practice:
- HBS
- Olin
- Cox
- CBS
- Kellogg
- Chicago
I know this shouldn't be a criterion for choosing your future school, but it could be helpful in picking your safety school. Moreover, this list might promote the practice, and hopefully other schools would follow!
