I will comment each design seperately. This regards #12.
The choice of athlete is quite good, also the color. The figure should approach the lettering instead of facing away - also the connection to academia is absent. Try also playing with the USG-font it seems a little Star Wars'ish.
this regards #7. We would to move away from using the letters USG as our main logo and see if we can establish a recognizable logo that transcends letters and is recognizable on its own.
nice touch with the star in #13. Could you invert the figure so that it points toward the lettering? also could you put an apple, a scroll, a book or an owl in the hand of the academically and physically active person?
I can see that I cannot even complete this comment before your next suggestion pops up - great work.
Regarding #16 - the idea with the book is really good and thank you for inverting the figure. Initial thoughts about the design is that we shouldn't put something in the hand of the figure as well as using the book. It is either or. I think the book idea i s a really good one. Try also to enlarge the figure so that it seems to interact with the lettering.
you have withdrawn #16 - that was quite good with the book idea - you should keep that in. The figure should be more raised - he seems either really old or really tired. The USG-font is a little box like. Could you change it to something more rounded.
Get some sleep ;0) - the competition ends in 6 days so there is still time to get it right.
regarding #16. looks nice. Remove what the figure is holding in its hand. Also make it more clear that it is a book that the person is jumping out of. Please also make the figure bigger. Very nice work so far.
nice work on #35 and #36. I really like that you have changed the font to a more rounded one. Also the icon has improved imensly. Ultimately I would like the Icon to be bigger - would that be possible? And try changing the colors in the figure on #35 to be the same as the USG-font all over arms body and legs.
