The 1/3, 5/7 rule is a structured study technique designed to boost memory retention and optimise revision efficiency. The technique is popular among students and high achievers. It combines spaced repetition with balanced task prioritization to align with how the brain naturally learns and forgets.

Core Principles:

1/3 Rule: One-third of your study session is spent on learning new material, while the remaining two-thirds focus on reviewing previously learned content and active practice that includes solving questions or explaining concepts.
5/7 Rule: You study or review a topic five out of every seven days, ensuring consistent exposure without burnout. This spacing combats the brain’s forgetting curve by reinforcing memory just before information fades.

Key Components of Daily Implementation:

15–20 minutes: Engage with new material like notes, readings, videos.
20 minutes: Revise concepts from the past 5–7 days.
Remaining time: Apply knowledge through practice questions, flashcards, or teaching aloud.

Benefits:

Enhances long-term memory retention through spaced repetition.
Reduces cramming and exam stress.
Promotes healthier study-life balance by incorporating rest.
Builds confidence and subject mastery over time.

The 1/3, 5/7 rule is not about studying longer: but studying smarter by balancing new learning, consistent review, and strategic rest to lock knowledge into long-term memory.
