I recognize that this section of my portfolio might be a little weird: why the heck are you going to show us documentation of your assignments? But, in my entire degree they asked us to format our documentations using design tools (mostly indesign), and I loved it! It really took my typography and layout skills to the next level.
I really put an effort in these documents, most of the time. Designing them taught me even more than the material itself. I feel that the designing of these documents allowed my visual skills to truly shine.
