Considering the fact that the information we receiving with course is 100% practical, I assume that the things like survey, design statement and other documentation supposed to be done for each project even if there is nothing said in the student project book. I would not submit them if not required, I just find if very useful for setting up the whole workflow. In the document called “Glossary of submissions” I found the confirmation for my thoughts – things like backup materials or work book are not mentioned in the project book, but it does really makes sense to collect and systematize all interim materials for each particular project for the future reference.
As for the school projects I think it is more convenient to store the information as a papers in folders. As for the real life projects I am planning to keep them in digital format just to save the space in my office (I will have my own office at some point) and trees in forests. The Evernote is definitely the best software for that.
The folder name for a school work consists of number of project from project book_date started_date finished_name of Client_title of project.
Example: 4:1_16.03.11_15.06.11_Wedding Organizer_Home office

You have grasped the point entirely. What you suggest is very reasonable and practical for a designer-to-be.
Thank you, Galiya. You welcome to use it as a template for your working materials if you like. Probably you will find room for improvement here eventually, I would be happy to hear about it.
