The Secret of Repetition

February 20, 2026  ·  4 min read

Ask most people how to memorize vocabulary and they'll say: repeat it. That's partially right, but the type of repetition matters enormously. Here's why varied repetition beats simple drilling every time.

The forgetting curve

German psychologist Hermann Ebbinghaus showed in the 1880s that we forget newly learned information rapidly. Roughly half of it within an hour, and most of it within a day. The antidote is review at spaced intervals. But spacing alone isn't enough; the way you review also matters.

Varied repetition vs. drilling

Drilling, writing a word 20 times, creates a shallow memory trace. You remember the act of writing, not necessarily the word. Varied repetition, encountering the same word in 6 different contexts and exercise types, forces your brain to retrieve and reconstruct the word each time. This retrieval effort is what makes the memory stick.

How our sets use this principle

Every Quicklearnsheets set uses the same 10 to 12 words across 6 different exercises: recognition, matching, letter pairing, writing, unscrambling, and free recall. Each exercise type activates a different cognitive process, and together they create a robust, multi-layered memory for each word.

The role of spacing

For best results, don't complete all 6 exercises in one sitting. Spread them across a few days. This allows the forgetting curve to work in your favour, you review just as the memory is starting to fade, which strengthens it more than reviewing when it's still fresh.
