12-month FLEX vocabulary plan: how much to learn and when
FLEX applicants often ask how many English words to learn before tests, essays, and interviews. FLEX reviewers care more about clear writing and calm speaking than a huge list you cannot use. This guide pairs monthly word targets with the FLEX 12-month prep calendar.
What “enough English” means for exchange
You do not need university-level vocabulary to succeed on a high-school exchange. You need roughly B1 to B2 skills: explain your day, discuss school subjects, handle interviews, and write a short personal essay without constant dictionary use.
A practical range for many finalists is about 2,500 to 3,500 words they can actively use (not only recognize on a flashcard). That includes phrases and collocations, not isolated entries.
If you already study English at school, count review and depth, not only “new” words. Turning passive knowledge into speaking confidence matters as much as adding cards.
Simple weekly targets (quality over quantity)
A sustainable pace for most students is 6 to 10 useful items per day: a word plus an example sentence you wrote yourself. That is roughly 40 to 70 per week, or 150 to 280 per month, if you study five to six days a week.
Learn in sets: “volunteer at a shelter,” “stay after class,” “ask for feedback,” not random lists from the internet. Essay and interview topics repeat; reuse the same vocabulary in writing and speech.
Use spaced repetition (Anki, Quizlet, or a notebook with dates). Words you miss twice go back to daily review; words you use correctly in an essay move to monthly review.
Months 12 to 10: foundation (about 400 to 600 new items)
Focus on high-frequency verbs, school life, family, hobbies, and community service. Aim for 5 to 7 new items on study days, plus 15 minutes of graded reading.
Monthly check: can you describe your typical week in 90 seconds without long pauses? If not, reduce new words and practice retelling instead.
On IQ Abroad, read two essay examples per week and note phrases candidates use to show growth, not fancy synonyms.
Months 9 to 7: build (about 500 to 700 new items)
Raise to 8 to 10 items on study days if review stays under 20 minutes. Add opinion language: “I realized,” “I used to think,” “what mattered was.”
Pair vocabulary with one timed writing task per week (20 to 25 minutes). New words only count when they appear in your draft.
Start interview story banks: five situations (conflict, teamwork, failure, leadership, culture). Each story needs 10 to 15 reliable phrases.
Months 6 to 4: application season (maintain, do not cram)
Shift time from long word lists to essay revision and program-specific reading. Add 3 to 5 items per day maximum; most energy goes to editing your own sentences.
Build a personal “essay toolkit” of 30 to 40 phrases you trust. Readers notice repeated natural language more than rare words used incorrectly.
If your process includes an English test, drill task formats (reading speed, grammar patterns) rather than 50 new words the week before the exam.
Months 3 to 1: interviews and finals
Stop expanding the list. Drill pronunciation and fluency with words you already know. Record answers; replace filler pauses with shorter sentences.
Practice explaining your country, school, and goals using simple vocabulary. Clarity beats complexity in panel interviews.
After selection: before departure
Learn host-country daily life terms: transportation, meals, classroom phrases. 3 to 5 items per day is enough alongside emotional preparation.
Keep journaling in English. A short paragraph nightly stabilizes vocabulary better than a final-month sprint.
