Platform Manual
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.
A quick overview before you touch anything.
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.
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.
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.
The landing is one big grid: each language group is a panel, each panel lists that group's exams.
English, 中文, 日本語, 한국어, Tiếng Việt, Bahasa Indonesia, Español, Português. Each panel spans one row and lists countries + exams inside.
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.
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.
No signup. The browser holds a cookie so you can leave and come back to the same attempt.
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.
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.
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.
Two paths: email + password, or Google. Both land you at "active" — but email needs verification first.
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.
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.
Same modal → "Continue with Google". Google verifies the email for us, so the account is active immediately — no email round-trip.
One question at a time, timer running, autosave on. Six question types.
Total, PASS/FAIL badge, per-question breakdown.
The whole UI switches with one click — but so do the exams shown, since each is anchored to a language group.
Click "EN / KO / JA / ZH / …" to open the language picker. Pick a language and the page reloads in that locale.
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.
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.
Someone shared a /i/{token} URL with you. Here's what happens when you open it.
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.
Same timer, same question types, same autosave. Submit → you see the result page.
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.
The hamburger menu (☰) opens after you sign in.
Yes, for 7 days, keyed by your browser cookie. Sign up before the window expires if you want to keep them.
The server auto-submits with whatever answers you have committed. No penalty beyond that — your partial score is your score.
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.
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.
Everything on this platform is in KST (Asia/Seoul, UTC+9). No conversion — same value for everyone.
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.
