Roadmaps.

what to learn, in what order, and where it usually goes wrong

The notebooks are organised by topic, which is how a writer organises material. You arrive with a goal instead. A roadmap reorders the same ground by goal: every stop points at the canonical reference, says plainly whether we have written anything on it, and offers an hour when reading is not going to be enough.

More maps are being drawn. Databases and the final year project are next, and each one only ships when it is honest about what we can actually take you through.
