We're the team behind Flips, a flashcard app built around the idea of showing you a word right before you forget it. If you're studying for a language proficiency exam, you've probably hit this wall: “Each level has so many words that by the time I reach the end of the list, I've forgotten the beginning.”
Proficiency exams are organized into levels or grades, and each level adds its own band of required vocabulary. The amount is large, and that's exactly what makes the usual approach break down. In this article we'll explain why level-by-level vocabulary slips away, and how to study it so that no part of the list gets left behind.
Why each level's vocabulary is so easy to forget
The range per level is wide — often hundreds of words you're expected to know to pass. When you try to cover all of them evenly, going through the whole list start to finish, the words you studied first have already started fading by the time you reach the last ones. You finish a pass feeling like you've forgotten as much as you learned.
The deeper issue is that a flat, even pass treats every word the same. Words you already nailed get the same airtime as the ones you keep missing. With a fixed exam date approaching, that's time you can't afford to waste re-confirming words you already know.
Put your time where you're weak
The fix is to stop reviewing evenly and instead concentrate on the words you actually keep getting wrong. A word you answer confidently doesn't need to come back for a while; a word you miss needs to come back soon, and often. Tilting your reviews toward your weak words is how you cover a huge level-specific list without drowning in it.
The problem, of course, is keeping track. Across hundreds of words per level, you can't realistically remember which ones you're weak on and when each is due. That's the part we built Flips to handle. It calculates the next review time for each word individually — correct answers push the interval wider, while words you miss or feel unsure about come back sooner. Your weak words automatically get more reps; your strong ones step out of the way.
Build your own deck for the level you're targeting
Because exam vocabulary is level-specific, it helps to study exactly the set you need. In Flips you can create your own wordlist for the level you're targeting, alongside the built-in standard decks for English, Spanish, Chinese and more. That way your reviews stay focused on the band of vocabulary that matters for your next test, not a generic mix.
You answer with recall, not recognition. Card Mode has you remember the meaning before flipping the card; Quiz Mode gives you four choices with instant feedback. Both make you retrieve the word from your own memory (active recall), which is far stronger than passively rereading a list. And when reviews come due, Flips can notify you, so a busy week doesn't quietly undo your progress.
A proficiency exam's vocabulary feels overwhelming because it's large and you're trying to hold all of it at once. Narrow your focus to the words you're weak on, let the timing be managed for you, and a level that felt impossible becomes a list you can actually finish.

Why do I forget the early words by the time I finish a level's list?
Because the range per level is large, and an even start-to-finish pass takes long enough that the first words fade before you reach the last. The fix is to return to fading words sooner instead of waiting to loop the whole list.
Should I review every word the same amount?
No. Words you already know don't need frequent review; words you keep missing do. Concentrating your time on weak words is how you cover a large level-specific list efficiently before exam day.
Can I study just the vocabulary for the level I'm taking?
Yes. In Flips you can create your own wordlist for your target level alongside the built-in standard decks, so your reviews stay focused on exactly the band of vocabulary you need.
How does Flips put more time on my weak words?
It schedules each word individually. Correct answers widen the interval; words you miss or feel unsure about come back sooner. So weak words automatically get more reps without you tracking anything.
