When it is time to learn new tuls/patterns/hyungs/whatever variety of form you practice, do you learn them by yourself from a book and then go to your instructor for help, or does your instructor teach them to you as s/he feels you are ready to learn them?
For myself, I wait until my sahbum teaches me, and then use reference books to help me practice and remember - then I go to my instructor for additional assistance and critiques. Even with a complete version of the Encyclopedia, I would not want to teach myself new tuls - I know it's been done, but I would much rather wait until my sahbum says I am ready for the next piece(s) and learn from him; there's just too much it's possible to miss when attempting to learn from a book, and the last thing I need is more bad habits to break!
