That's great to hear, thanks for the response! That sounds about as far as I got, so I think probably I was closer to 200 pages, not 300. It was just so incredibly boring. I was making it through maybe 4 pages a day if I was lucky. And all the material was so similar, it wasn't like you got through one part and then built upon it to something very different; it was more of the same with only a small difference. So no new-topic-energy-burst at the start of a new section.
Yeah it’s quite a slog. I think I averaged 10-20 min per page of progress. I intend to return and finish it but it will take me ages.
It’s not a prerequisite at all though. Crafting Interpreters is pretty high level, in comparison.
