How to use 25test

25test is a mini-trial platform for the world's high-stakes exams. Twelve countries, eight languages, twenty-five questions per trial. This page walks through every screen you will see, from picking a country to reading your score.

1What is 25test?

A quick overview before you touch anything.

One trial = 25 questions

Every trial is a compact 25-question extract of a real exam — Gaokao, SAT, CSAT, Kyotsu, JEE, NEET, THPT, UTBK, EXANI-II, ENEM, A-Level, LET, MDCAT. Enough to feel the exam without spending three hours.

Twelve countries, eight languages

The landing page groups exams by their home country and shows them in your language. Native names appear alongside English (e.g. 수능 (CSAT), 高考 (Gaokao)) so you can find yours at a glance.

You can start without signing up

Guest trials work. Your progress is kept in a browser cookie so you can pause and return. Signing up later lets you save history, invite friends, and build your own bank.

Why 25 questions? Long enough to reveal weak topics, short enough to finish in a lunch break. If you want a full-length practice, sign up and build a custom test — the platform supports any question count.

2Finding your exam on the landing page

The landing is one big grid: each language group is a panel, each panel lists that group's exams.

Language groups down the page

English, 中文, 日本語, 한국어, Tiếng Việt, Bahasa Indonesia, Español, Português. Each panel spans one row and lists countries + exams inside.

Click an exam card to start

Cards show the exam's native name plus the English name in parentheses. Tap once — you land on the trial start page for that exam, no login required.

Sub-subjects expand inline

Exams like SAT (Reading & Writing + Math) or Kyotsu (Kokugo + Sugaku + Rika + …) have a ▸ arrow. Click to see the list; each subject launches its own 25-question trial.

Tip — the search box The search field on the top-right filters exam names in real time. Try "sat", "수능", or "共通" — the grid narrows immediately.

3Taking a trial as a guest

No signup. The browser holds a cookie so you can leave and come back to the same attempt.

Landing → exam card → Start

Click any exam card. The trial start page shows what you're about to take (category, number of questions, time limit). Hit "Start" and the timer begins.

Your progress lives in a cookie

While you attempt, every answer is autosaved to the server keyed by your guest cookie. Close the tab and reopen the same exam link within a week — you land back on the exact same question.

Guests keep the result page

After submit you get the same score screen a member would see. But guest attempt history is purged after 7 days by scheduled cleanup — sign up before then if you want to keep it.

Why is the guest window 7 days? Cookie-only accounts have no email fallback, so lingering data is a small privacy risk. Seven days is enough to finish, review, and decide whether to sign up.

4Sign up & email verification

Two paths: email + password, or Google. Both land you at "active" — but email needs verification first.

Sign up with email

Landing → "Sign in" → "Create an account". Enter name, email, password. Submit → you land on the "Check your inbox" page. Nothing else works until you click the link in the email.

Click the verification link

The email carries a signed URL valid for 24 hours. Clicking flips your account to active, logs you in, and drops you back on the landing page.

Or sign up with Google

Same modal → "Continue with Google". Google verifies the email for us, so the account is active immediately — no email round-trip.

Didn't get the email? "Resend" is available once per minute on the verify-pending page. Also check your spam folder — noreply@25test.com may land there on first send.

5Inside the trial

One question at a time, timer running, autosave on. Six question types.

The six question types

MCQ single Pick one of several choices. Click the radio.
MCQ multi Pick multiple correct choices. Partial credit is not given — all-or-nothing.
Ordering Drag items into the right sequence. Order matters.
Fill in blank Type the missing word or number. Whitespace-trimmed, case-insensitive.
Short answer A few words. The reference answer must match; explanation is shown on result page.
Open answer A paragraph. Scored by the AI rubric — you'll see the AI's reasoning on the result page.

Timer, autosave, submit

  1. The countdown timer sits on top-right. When it hits 0, the server auto-submits.
  2. Every answer is saved the moment you commit it (click, drag-end, type). No submit-per-question button — moving to the next question is enough.
  3. Click "Submit" any time. You can't come back to the same attempt after submitting; scores are frozen.
Don't refresh mid-attempt Refresh is safe — your answers are on the server — but the timer resumes exactly where it was. If you're near zero when the network hiccups, expect an auto-submit soon after.

6Your score & the result page

Total, PASS/FAIL badge, per-question breakdown.

What the page shows

Total score Sum of points earned. Displayed as "X / Y" where Y is the max.
PASS / FAIL badge Comes from the test's pass score threshold. If your total ≥ threshold → PASS.
Time spent From start to submit. Timed-out attempts show as (auto)-submitted.
Per-question rows Your answer, the correct answer, the points column. Failed rows are marked red.
Explanations If the question had an explanation, it renders beneath the correct answer.
Tip — print your result "Print" opens a clean, monochrome view suitable for saving as PDF. Good for archiving or emailing to a teacher.

7Language & region

The whole UI switches with one click — but so do the exams shown, since each is anchored to a language group.

The language button (top-right)

Click "EN / KO / JA / ZH / …" to open the language picker. Pick a language and the page reloads in that locale.

Fonts adapt automatically

CJK scripts (한국어, 中文, 日本語) load their own font stack — Noto Sans KR, Noto Sans SC, Noto Sans JP — so characters render at the right weight and metric. Diacritics for Vietnamese/Spanish/Portuguese are handled by Inter's extended set.

Question content stays in native

The UI chrome switches, but the exam questions render in the language the question was written in. A 수능 국어 question stays in Korean regardless of your UI locale — that's the whole point.

8Joining via an invite link

Someone shared a /i/{token} URL with you. Here's what happens when you open it.

Open the invite URL

The link goes straight to the shared test's start page — no login required. If you're signed in, the attempt is tied to your account. If not, a guest cookie is issued.

Attempt like any other trial

Same timer, same question types, same autosave. Submit → you see the result page.

The class owner sees your attempt

Whoever handed you the link (the owner) sees a row in their "takers" dashboard — your score, time spent, per-question breakdown. Guests are shown as anonymized cookie IDs.

Sign up to keep the record If you took the attempt as a guest and want to see it later, sign up within 7 days using the same browser — the cookie can be linked to your new account.

9Your dashboard (after login)

The hamburger menu (☰) opens after you sign in.

What lives under the hamburger

My workspace Dashboard summary, question bank, tests, AI tools. This is the owner side — used when you want to build your own class.
Records My results (your own attempts), People who took my tests (attempts on classes you own).
Account Language preference, AI keys, sign-out.
Want to build your own class? See the dedicated guide at /guide/class — it explains categories, topics, tests, and invite links from an owner's POV. /guide/class

10FAQ

Are guest scores saved?

Yes, for 7 days, keyed by your browser cookie. Sign up before the window expires if you want to keep them.

What happens if my time runs out?

The server auto-submits with whatever answers you have committed. No penalty beyond that — your partial score is your score.

Can I retake the same trial?

Yes — you can attempt any published test as many times as you like. Only your latest attempt is the "current" one on the result page.

How is PASS decided?

Each test defines a pass score threshold. If your total ≥ threshold you get PASS. Public exams follow the exam-authority convention; classes you enter follow whatever the class owner set.

What time zone are attempt timestamps in?

Everything on this platform is in KST (Asia/Seoul, UTC+9). No conversion — same value for everyone.

Where can I read more about hosting my own class?

See /guide/class. It explains the owner side (categories, topics, questions, tests, invite links) in detail. /guide/newcomer explains what you unlock by signing up.
