[quote name='BlazeP']You do realize that there are 387,420,489 possible combinations, right?[/QUOTE]
I believe there are only 54 choices - (3 choose 1 - for pre-service) x (3 choose 1 - for psychological) x (6 choose 1 - for class). And if you take the hint I gave into consideration, 20 more choices are eliminated because they don't have any one of default Shepard's profile elements in it. That leaves 35 choices in total. Had I been more precise to say that 'only one category is the same', that would eliminate another 10 choices which overlap with default Shepard in 2-3 categories.
Anyways, we have two winners! The codes have be sent out. Thank you all for trying.
My Shepard is an Infiltrator, Colonist and Sole Survivor.
