The study habits that actually work (and the popular one that does not)

Most of us study by re-reading and highlighting, because it feels productive. A widely cited review of learning research found those are among the weakest techniques. Better ones exist, and they feel harder, which is the point.

The habits with strong evidence

• Test yourself. Close the book and recall the answer, write the steps from memory, or redo the task without the tutorial. Retrieval strengthens memory more than re-reading does.
• Space it out. Reviewing a little across several days beats cramming for hours. Try revisiting a topic after a day, a few days and a week.
• Mix topics. Practising different problem types in one session feels slower, yet it teaches you to choose the right method.
• Explain it aloud. Teach the idea to someone, or to an empty chair. Gaps in your understanding show up immediately.

Applying this to software skills

Watch a tutorial once, then close it and rebuild the result from memory. Where you get stuck is exactly what you have not learned yet. Keep a short list of those sticking points and review it the next day.

Twenty minutes of active recall every day will beat two hours of passive reading on Sunday.
