Plans / goal-first routes through the courses
Learning plans
What this isThe courses go deep on one subject. A plan starts from a goal and a time frame instead, and takes the steps from across the courses that get you there.
The plans
Each plan is a short, ordered list of course steps, with what to do in each and why it's there.
