Ultralearning
Scott H. Young
Ultralearning (2019) is Scott H. Young's case for intense, self-directed learning projects. He builds nine principles from his own experiments, such as working through MIT's computer science curriculum on his own in about a year. Its most useful core is to test yourself instead of rereading, to practise the skill in the form you'll actually use it, and to attack the one weakness holding you back. Read it for the method, not the heroics.
Most of us study in the way that feels productive: we reread, we highlight, and we repeat what we already do well. Young argues that the feeling and the progress often point in opposite directions.
The book in essence
Young became known for the "MIT Challenge." Using MIT's freely published course materials, he tried to pass the exams of a four-year computer science curriculum in roughly twelve months. He later spent a year learning four languages with his friend Vat Jaiswal while avoiding English. The book turns those projects, along with profiles of other intense self-learners, into nine principles: metalearning, focus, directness, drill, retrieval, feedback, retention, intuition and experimentation.
The principles that matter most are not new. They repackage well-established findings from learning research. Retrieval practice, also called the testing effect, consistently beats rereading. Deliberate practice explains why years of comfortable repetition hit a plateau. Research on transfer shows that a skill learned in one context often fails to appear in another. Young's contribution is turning all of this into a project you can actually run.
There are honest caveats. The headline stories involve someone with unusual free time and stamina, and passing exams from published course materials is not the same as earning a degree. You don't need to go "ultra" to benefit. A few hours a week run on these principles will beat twice that time spent rereading.
Who it's for
- Self-learners preparing for an exam or a career switch
- Professionals who need a new skill (a language, coding, data analysis) by a deadline
- Anyone stuck on a plateau after years of "practice"
- Students who reread their notes and still go blank in exams
Who it's not for
- — Readers who want a deep tour of the research. Make It Stick by Brown, Roediger and McDaniel covers the science more thoroughly
- — People looking for a gentle, low-commitment habits book
Key lessons
01
Close the book: make retrieval your main way to study
Rereading feels like learning because the material becomes familiar, but familiarity is not recall. Young puts retrieval at the centre. Before you look, try to pull the answer out of your own memory. You can write everything you recall on a blank page, answer questions you made yourself, or explain a concept without notes. It feels slower and more frustrating, and that effort is exactly what strengthens the memory. The practical rule is to spend at least as much time testing yourself as you spend reading. Struggling first and then checking beats reading three times.
A nursing student in Leeds used to reread her pharmacology notes on the bus. She switched routines. Now she reads one drug class, closes the folder and writes the dosages and side effects from memory, then checks them in red. In the first week, half of each page was red. By the exam the red had shrunk to a few lines, and those were exactly the drugs she would have missed.
02
Practise on purpose, not on repeat
Once a skill feels comfortable, doing more of the same mostly just maintains it. Young's drill and feedback principles say progress returns when practice has four features. It is narrowed to one specific component, done with full attention, checked quickly against a clear standard, and pitched just beyond what comes easily. That is less pleasant than playing the whole piece or the whole match, which is why most people avoid it. Here is a simple test. If a session felt easy and you can't name what got better, it was repetition, not practice.
A weekend footballer had played five-a-side for eight years with the same weak left foot. Instead of just playing another match, he spent twenty minutes before each game hitting left-footed passes against a wall. He counted the clean returns out of fifty and filmed the last ten. His count rose from 19 to 37 in six weeks, and his teammates noticed before he told them.
03
Map the skill, then practise where it lives
Young calls the first step metalearning. Before you start, find out what the skill really demands, how others learned it and what good performance looks like. Then comes directness: practise in the situation where you will use the skill, or as close to it as you can get. Many learners spend months on a neighbouring activity, such as vocabulary apps instead of conversation or tutorials instead of building. Then they are surprised when it doesn't transfer. Spend a few hours mapping before you spend a few hundred practising.
A product manager moving to Madrid had a 400-day streak in a language app but froze in her first meeting. She asked two Spanish colleagues what meetings actually required: numbers, dates and polite disagreement. She cut her app time in half and did weekly mock meetings with a tutor, using her real agendas. Within two months she was leading the Monday status call.
04
Design your own learning project
The book's real tool is the project: a defined skill, a deadline and a weekly rhythm. Strong projects cycle between three modes. First, do the real skill to see where you actually stand. Next, drill the one weakness that limits your overall performance, on its own. Then, a few days later, test what stuck without any help. After that, go back to the real skill. Keeping the scope small matters more than going "ultra": six to twelve weeks at a few hours a week is enough. Write the plan down before you begin.
An accountant learning SQL gave himself eight weeks. Each Monday he rebuilt one real monthly report as a query. When joins kept breaking his results, he spent fifteen minutes a day on join exercises alone. Every Friday he wrote one report from scratch with no notes or searching. By week six, the Friday test took twenty minutes instead of two hours.
Try this today
Pick something you studied this week. Close every note, set a 10-minute timer and write down everything you remember on a blank page. Then check it. The gaps you find are tomorrow's study plan.
Quick check
You have one hour before an exam on material you've read once. According to Ultralearning, what's the best use of that hour?
Why does Young insist on directness?
