BSPS is organized as a dependency graph, not a flat list. Some modules require knowledge from others.

Active reading: Every module has a lab or benchmark. Run it. The numbers are more memorable than prose.
Cross-references: Each module links to the theory that explains it. When you hit a concept you don't understand, follow the link to the foundational module and read that first.
Revisit: The first time you read a module, some parts will be abstract. After running the lab and writing production code for a few weeks, re-read the module. The second reading is always more valuable.
01-mathematics, 03-os, 04-networks): Read carefully. The math and OS concepts underpin everything else.07-core-backend): Read, then immediately run the code examples. Change the parameters. Break things.in this section
