Hello, Gavin Two weeks after creating the "Last distillation/"D" list from a heading, I should review it - but of those words which I STILL can't remember, from that "D" list -- are they suppoed to go into another book, or what? IOW, to use the Goldlist method, I'm supposed to daily create "Headlists" opf 25 words/phrases/expressions, each daily list, after a series of 2 weeks review, of "A", "B", "C" lists will narrow down eventually to "D" lists from each headlist. If, say three, of the expressions from the "D" list I still can't recall - what do I do with them? Many thanks!
