I'm slightly baffled by the structure: "[We will be] completing 3 exercises from each chapter of SICP over 6 weeks, one chapter a week after the kickoff." Firstly, my edition and the linked edition only have 5 chapters. Secondly, it's unclear if it means those 5 sections as the chapters, or the smaller subsections (1.1, 1.2, etc). If they mean the big chapters, then this seems way, way, too fast (with not enough exercises), and if it's the subsections then it still seems like too few exercises. I've been doing one subchapter each week, completing at least half the exercises in each section. It's been a pretty good pace, I think, and I'd probably recommend it to people with similar amounts of free time to me. I'm coming from a maths background and have no previous CompSci experience (save a tiny bit of Python).
