Yes, but writing questions can take up so much time, in fact the time you "saved" photoreading can be "Wasted" on writing questions.
And then, once again I say, my purpose is to understand the mechanics of photoreading, so if I have no idea what it is, how can I quiz myself if I have no idea.
It is like sending a janitor out to interview Donald Trump on buildings, how can such a person give Donald a intelligent question?
