Dear Scott and Julian,
Thanks for the advice!
Julian -if I'm getting you right, you would perhaps keep a list of material that has been learned (as matched against the syllabus, e.g.) as a project support material, and you would actually stick to classic GTD in terms of learning objectives, using NAs to track current learning points. This sounds very interesting, especially you recommendation with respect to energy levels -one thing I definitely need to implement better into my current system.
Out of curiosity, do you or anyone else have any experience dealing with the basic science coursework through mind maps? I'm not fully comfortable yet using a mind mapping software (or any form of electronic tools, for that matter) to take notes in classes; but I'm thinking it might be an interesting idea to use mind maps when skimming over a lecture's notes as a preview and/or review.
