$900/year for textbooks sounds like a dream.
Us architecture students--in undergrad OR grad--can pay upwards of $1,000 a SEMESTER for studio supplies; the first semesters are devoted to buying basics like rulers, a drafting board, getting basic computer programs like AutoCAD, Vectorworks, etc. The subsequent ones are all about model supplies, which get used up very quickly.
And that's STILL on top of buying books for classes other than studio.
