Frequently asked questions
Which level should I start with?
If unsure, run Adaptive mode once — it converges on your level in 12 questions. Then drill the level it reports until you score 9–10, and move up.
Do wrong answers show the correct meaning?
Yes — the correct option is highlighted after every answer, so each round doubles as a mini vocabulary lesson.
Are the meanings shown in my language?
On the English page meanings are short English definitions; on the Korean and Spanish pages they are translations — ideal for learners.
How many new words a day is realistic?
For lasting learning, 5–20 new words a day is the sustainable range for most people — beyond that, forgetting tends to outpace learning. A better daily target is mixed: a handful of new words plus quick review of older ones. One or two 10-question rounds here each day fits that pattern nicely.
What is spaced repetition, and how do I use it with this quiz?
Spaced repetition means reviewing material at growing intervals — a day, then a few days, then weeks — timed to just before you'd forget it. It's one of the best-documented techniques in learning research. With this quiz, simply replay the same level on that schedule: missed words resurface, and each successful recall strengthens them.
Is quizzing myself really better than rereading word lists?
Yes — memory research consistently finds that retrieval practice (pulling an answer from memory) beats passive rereading, an advantage known as the testing effect. Even wrong answers help, because the immediate correct-meaning feedback arrives exactly when your brain is most receptive. That's why this quiz corrects you on the spot.
