为什么在这里练习Why practise here
真题，不是仿题Real papers, not lookalikes
全部试卷来自剑桥雅思 1–21，与考场同源。练的每一套，都是考过的那种题。Every paper comes from Cambridge IELTS 1–21 — the same source as the exam room.
分数换算不含糊Conversion done properly
听力、阅读各用自己的换算表，从不混算。下面就能亲手拖一拖。Listening and Reading convert on their own tables, never blended — drag the converter below and see.
口语和写作也有人批Speaking and Writing get marked too
AI 考官按评分维度逐项给分、逐项讲改法 —— 这两科恰恰是自己最没法对答案的。An AI examiner scores criterion by criterion and shows what to change — precisely the two papers you cannot self-mark.
错题不白错No mistake is wasted
每道错题自动进错题本，按 1、3、7、16、35 天原样回来重考，直到你真的会。Every miss is filed and re-tested, unchanged, at 1, 3, 7, 16 and 35 days — until it sticks.
两个科目，两种换算表Two papers, two tables
听力和阅读的原始分换算表不同。同样答对 26 题，两科相差半分档。拖动看看。Listening and Reading raw scores convert on different tables. The same 26 correct answers sit half a band apart. Drag and see.

两张表分别换算，再按 13 种题型拆开正确率 —— 告诉你差的不是“一分”，是哪几类题。Each paper converts on its own table, then your accuracy is split across 13 question types — so what you are missing is not “one point”, but specific kinds of questions.
攻克你最薄弱的题型Fix your weakest type
错题自动进错题本，按 1 / 3 / 7 / 16 / 35 天原样回来考你。Wrong answers go straight into a mistake notebook and come back to retest you, unchanged, after 1 / 3 / 7 / 16 / 35 days.
