We're the team behind Flips, a flashcard app built around the idea of showing you a word right before you forget it. A complaint we hear often from TOEIC studiers: “I keep grinding the vocabulary, but it just won't stick. And the more I try to cover, the less I seem to keep.”
TOEIC has a particular quirk: the words you actually need depend on your current score band. Someone aiming to move from 500 to 700 needs a different core set than someone pushing from 800 to 900. Trying to memorize everything at once is what makes it feel like nothing sticks. In this article we'll show a score-band approach that gets words to stay.
Start from the words that show up most
TOEIC rewards high-frequency vocabulary — business and everyday words that recur across the test. If your score is in a lower band, the fastest gains come from locking down those common words first, not from chasing rare ones you'll see once. Prioritize by frequency for your band, and each word you learn pays off on more questions.
The trap is trying to cram the entire frequency list in one push. You touch each word once, feel like you've “done” it, then forget most of it within days. Coverage without retention isn't progress — it just feels like it while you're doing it.
Pour your time into the words you keep missing
Once you've picked your band's core set, the words won't stick evenly. Some you'll get instantly; others you'll miss again and again. Reviewing both the same amount wastes your limited study time. The efficient move is to spend most of your reps on the words you keep getting wrong, and let the easy ones fade into longer intervals.
Doing that by hand is the hard part — you can't track which of hundreds of words are weak and when each is due. That's what Flips handles. It schedules each word individually based on the forgetting curve: get one right and its interval widens; miss it or feel unsure and it returns sooner. Your weak words automatically come up more often, while words you've mastered step out of the rotation.
Stack it up in the gaps of your day
Most people studying for TOEIC are also working or in school, without long blocks for study. The good news is that vocabulary suits short, scattered sessions perfectly — a few minutes on a commute or in a queue is enough to clear the words due right now. Because Flips always knows which words are due, five minutes of spare time turns into real, targeted review instead of aimless flipping.
The answering is built around recall. Card Mode has you remember the meaning before flipping; Quiz Mode gives you four choices with instant feedback — both pull the word from your own memory (active recall) rather than letting you skim and feel familiar. You can build your own deck of your band's target words alongside the built-in standard decks, and Flips can notify you when reviews are due so your spare-time sessions stay on schedule.
TOEIC vocabulary doesn't stick when you try to swallow it whole. Start from high-frequency words for your band, pour your reps into the ones you keep missing, and let the timing run automatically — and the score follows.

Which TOEIC words should I memorize first?
Start with high-frequency words for your current score band. Common business and everyday vocabulary recurs across the test, so each one you lock down pays off on more questions than a rare word you'll see once.
Why does my TOEIC vocabulary not stick even though I study a lot?
Usually because you touch each word once and move on, then forget most of it within days. Coverage without well-timed review isn't retention. Returning to fading words at the right moment is what makes them stay.
Can I study TOEIC vocabulary in short bursts?
Yes — vocabulary suits short, scattered sessions. A few minutes is enough to clear the words due right now. Flips always knows which words are due, so spare-time study becomes targeted review instead of aimless flipping.
How does Flips focus on my weak words?
It schedules each word individually. Words you get right move to longer intervals; words you miss or feel unsure about come back sooner. So your weak words naturally come up more often, with no tracking on your part.
