5. TEACH IT WITHOUT YOUR NOTES
Explain the idea aloud as if the other person knows nothing.
Do not hide behind technical words.
Whenever you pause, become vague or cannot give an example, you have found the part that needs another review.
3. MIX SIMILAR TOPICS
Do not complete 20 identical questions before changing the subject.
Mix different problem types together so your brain must identify which method belongs to each question.
This feels harder during practiceβwhich is often why it produces stronger learning later.
4. ASK WHY IT MAKES SENSE
After learning something, answer:
Why is this true?
How does it work?
What would change the result?
What is a real example?
What is it commonly confused with?
If you cannot answer, you probably recognize the information without understanding it.
2. SPACE YOUR REVIEWS
Do not study something five times in one day.
A practical starting schedule is:
Day 1
Day 3
Day 7
Day 14
Day 30
Adjust the gaps based on how difficult the material is and when you need to remember it.
1. RETRIEVE BEFORE REVIEWING
Close the book and write everything you remember.
Then reopen it and compare your answer with the source.
Trying to retrieve information strengthens memory more than repeatedly reading the same page.

THE INTERNET STILL HAS HIDDEN GEMS!!
These 9 websites solve problems people normally download separate apps.
Or pay subscriptions to fix.
Bookmark them before you need them:
9. TURBO AI
Turn lectures, PDFs, audio and videos into notes, flashcards and quizzes.

Use the generated material for active recall, but compare important answers with the original source. It has a free tier, while some features and limits require a paid plan.
5. WHICH ONE SHOULD YOU USE?
Use Astra when the problem is extremely difficult and failure is expensive.
Use Sol for coding, agents and complex workflows.
Use Luna for clear, repeatable tasks that happen thousands of times.
A smart system can use all three:
Luna handles the volume.
Sol handles the workflow.
Astra handles the hardest decisions.
π¨BREAKING: OPENAI JUST DROPPED GPT-6 SOL AND LUNA.
One is built for complex agents. The other costs almost nothing to run.
Here is what separates them ππ½ππ½
4. THE PRICE DIFFERENCE IS THE STORY
For the price of 1 million Sol output tokens, you could generate 20 million Luna output tokens.
That does not mean Luna replaces Sol.
It means simple, repeatable work no longer needs to run on an expensive model.
Use strong reasoning only where strong reasoning creates value.
