OK all I can tell you is how I feel about this shit.
Basic rule in art schools: argue with the teachers, not with the administration. Consider the director as a politician who runs the school. If you argue with the teacher it's ok but when you take it to the director, they think you wanna get someone fired. And I'm sure they're prepared for that stuff, and get you fired instead.
Also I personally don't even give a fuck about grades, because they're numbers on a paper and only a retard looks at them and not your work, when you try to get a job for example. I understand you might care if it brings trouble in some practical level (less money from government?) but other than that, grades are useless in art schools...Mostly because there are no instant-facts about what's good or bad. There are just things that matter that one should learn to see and analyze.
For example the logos/symbols you've made don't work in small sizes, the typography isn't very clear... They say you should always make a logo so that it's reasonably clear as a small, black and white version.
The typography squares are ok to me, personally don't like the colors as they're almost one per a square. you could've mixed red and blue for example and still keep it minimal, adding tension and whatever you might call it.
Interestingness.
and as a disclaimer I don't consider myself as a good graphic designer or anything else. I'm on 12 oz, right?
