It is difficult, but definitely possible. The key will be remaining mindful of the non-essay portions of the application (often overlooked by both other consulting firms and anyone applying on their own).
1) Transcripts:
For most MBA programs, you can just upload official copies of your transcripts. You won’t need the originals physically sent to the schools until after you are accepted. That’s simple enough. The part that surprises candidates is that you also usually have to upload the official transcripts from any study abroad programs, even if those courses and grades appear on your primary university transcript. With schools closing for the holidays, you should contact them immediately or get the transcripts as soon as the schools reopen.
