The most powerful and straightforward learning method on the planet

This may be the most effective, simplest, hardest to master, yet unbeatable learning method you’ll ever encounter.

This methodology comprises two parts: simplified into Formal Sciences and Social Sciencess

It draws from the Feynman Learning Technique, psychology, Scott Yang’s How to Learn Effectively, and practical experience.
I. Sciences
Practice-proven subjects include: (Mathematics, Statistics, Physics, Computer Science)
Definition: Begin with the end in mind.
That is, work backward from the final outcome to identify key concepts, achieving mastery through the process of deduction.
Practical Method:
For example, when studying a math course, gather all valuable materials and preview every concept extremely quickly (within one or two days) to establish a foundational understanding. Then…
Directly tackle the final exam papers/or begin working through/deriving specific conjectures and theorems. Whenever you encounter a problem, consult books & resources to find solutions… (Initial problem-solving may take considerable time, but will accelerate as knowledge accumulates)
After repeating this process, you will gradually find that you have mastered nearly all the required concepts. You will be able to solve specific mathematical problems and complete tasks within the allotted time.
For highly complex subjects (like calculus), apply a decomposition approach: tackle differentiation, integration, and other components separately using this method, then integrate them later.
II. Social Sciences
Practice-proven courses include: (Linguistics, History, Politics, Economics, Philosophy, Psychology, Sociology, and Anthropology)
Definition: Process mentally, follow logic
Process mentally: Imprint concepts onto your mind, then immediately output them. Build your cognitive map.
Method:
If studying a psychology chapter, review each key concept point by point. After finishing, close the book, take a deep breath, and relax for 30 seconds.
Take a blank sheet of paper and immediately write down everything you recall—as comprehensively as possible, attempting to establish connections. Continue writing until you can’t think of anything new for 3-5 minutes (try your best).
Only when you truly can’t recall anything more should you review the sheet and reflect on its accuracy:
Could my explanations be ambiguous?
Are there any gaps or misunderstood points?
Put away the sheet, reopen your materials, and continue studying. When ready, take another deep breath and relax for 30 seconds.
Set aside your materials again and write down any new insights.
You may build upon the previous sheet,
but it’s better to rewrite everything anew.
If rewriting—repeat until you can confidently explain every concept, its connections, and applications precisely
(Avoid cramming too little or too much at once; keep the entire process within 1-2 hours)
Regularly repeat this process, using mind maps & bullet lists to summarize
Requires active learning and focus; reinforce with consistent review.
During later reviews:
Connect key points sequentially—a few core concepts can lead to understanding a multitude of others.
Attempt to explain concepts yourself; you’ll find recall becomes remarkably clear.
Final note: All methods rely on a solid foundation; otherwise, they remain empty frameworks. This approach can help you construct the most magnificent skyscraper, but it may not necessarily help you lay the building’s foundation… Good luck!
