Find repeated error patterns first
Instead of correcting every grammar point, find the repeated error type that most affects understanding.
Grammar criterion
Grammar blocker repair is not making every sentence longer; it is keeping longer sentences under control.
GRA blocker repair needs both range and accuracy because many learners try to show complex sentences and make a clear point messy.
Repair errors that affect understanding first.
Errors have weight
Minor errors may not cap the essay, but repeated errors that stop the reader affect the diagnosis.
Complex sentences should serve the point
A complex sentence is not better unless it clarifies cause, concession, or comparison.

雅思写作批改看懂了，下一篇还是不会改？提交一篇真实 IELTS Task 2，先看保守参考分数区间、主卡分点和原文证据；由你自己重写一段、完成整篇第二稿，再对比修改前后变化。首次合格诊断免费；确认确有主卡分点后，可一次性选择 7 天 ¥29 或 31 天 ¥99 写作修复期，一次只进行 1 轮且不自动续费。
Writing criteria
了解 IELTS Writing criteria 时，不要只背 TR/TA、CC、LR、GRA。更有用的是把每项标准转成可诊断的证据和下一次重写步骤。
Grammar 6 vs 7
IELTS Grammar 从 Band 6 到 7，常见差距不是句子不够长，而是复杂句、从句、主谓和标点在压力下是否稳定。
Grammar accuracy
IELTS Writing 的语法评分看 range 和 accuracy。复杂句如果错误频繁，会比稳定的简单句更影响读者理解。
Band range diagnosis
IELTS Writing band score checker 不应只返回看似精确的分数。提交题目和作文后，更值得关注的是保守分数区间、TR/CC/LR/GRA 四项判断、最影响目标分的主卡分点及原文证据。把这些信息转成下一版重写步骤，用修改前后变化判断反馈是否有效；结果不替代官方 IELTS 评分。
AI feedback score-gap diagnosis
ChatGPT 或 AI 给出雅思写作分数、修改建议或改写文本后，先别直接照抄。把反馈当作线索，回到题目和原文核对它是否指出 Task Response、Coherence、词汇或语法中的主卡分点，并要求具体证据。再把优先问题收窄成下一步重写步骤，判断修改是否真的缩小目标分差距，而不是只让文字更漂亮。
Writing9 alternative
找 Writing9 替代工具时，先问它是否给出保守分数区间、主卡分点、原文证据和下一步重写步骤，而不是只看界面或范文数量。
