Spaced repetition: beating the forgetting curve without long hours

Almost everyone forgets quickly after first learning something. A student who studies a topic on Monday may have lost much of it by the weekend. This is normal, and it is why last-minute cramming feels so hollow.

Spaced repetition is the practice of reviewing material at increasing intervals: a day later, three days later, a week later, a month later. Each review is short, and each makes the memory more durable. Decades of memory research support spacing as one of the most reliable learning techniques.

Why it helps students with ADHD

• Working memory is often weaker in ADHD, so information needs more repeated exposure.
• Short reviews fit short attention spans.
• It removes the pressure of last-week panic, which is a bad time for any student and a worse one for those who rely on urgency to start.
• It rewards consistency over intensity.

How to do it simply

You do not need a complicated system.

• After learning a topic, plan a quick review the next day.
• Repeat after 3 days, then a week, then two or three weeks.
• Use flashcards, a quiz or a one-page summary for each review.
• If you got something wrong, bring it back sooner.

Using flashcard systems

Many apps schedule reviews automatically. A commonly used algorithm called SM-2 gives each card an interval that grows when you answer correctly and shrinks when you do not. You do not have to remember what to review; the system tells you what is due.

Tips

• Keep daily review short: 10 to 15 minutes.
• Review before learning something new, as a warm-up.
• Do not skip a day because the pile has grown; do a portion and keep moving.
• Mix subjects so you are not reviewing only your favourites.

ZEKO's Smart Flashcards use SM-2 spaced repetition to schedule each card for when you are about to forget it. If you miss a few days, the next session starts with an easy comeback path instead of a mountain of overdue cards.
