A quick one here about font size. The class seems to prefer the font size small when reading ebooks because, according to (at least a few of) them, the prospect of having a large number of pages left because of a larger font size (e.g. ’50 pages left in this chapter’ vs. ‘5 pages left in this chapter’ at a smaller size) makes it much more difficult to read (not physically but in terms of mentally preparing to read / getting through it). That never would have occurred to me.
