What to do if your mock test score is unstable / 模考分数不稳定怎么办？
The most stressful mock-test pattern is not always a low score. It is a score that jumps up and down. 最让人焦虑的模考情况，不一定是一直低分，而是分数忽高忽低。
One day Speaking is enough, the next day Listening drops. One mock test is close to the target, the next one is far away. 今天口语够了，明天听力掉了；这次接近目标，下次又差很多。
Do not only look at Overall 不要只看 Overall
PTE Overall is not a simple average of Speaking, Writing, Reading and Listening. Integrated tasks can affect more than one skill, so one unstable task can move several scores. PTE Overall 不是听说读写四项的简单平均。综合题型会影响多个技能，所以一个题型不稳定，可能带动多个分项一起变化。
RS affects Speaking and Listening. SWT affects Writing and Reading. WFD and SST affect both Listening and Writing. RS 影响 Speaking 和 Listening；SWT 影响 Writing 和 Reading；WFD 和 SST 影响 Listening 和 Writing。
Pattern 1: the same skill is weak every time 情况 1：每次都卡同一项
If the same task or skill is weak every time, stop doing random mock tests and train that weakness directly. 如果每次都是同一个题型或分项弱，不要继续随机刷模考，要做专项训练。
For example, repeated WFD spelling errors need dictation and spelling review, not another full mock test immediately. 比如 WFD 拼写反复错，需要听写和拼写复盘，而不是马上再做一整套。
Pattern 2: a different skill drops each time 情况 2：每次差不同分项
If a different skill drops each time, check full-test execution: fatigue, timing, attention, stress and task switching. 如果每次掉的分项都不一样，要检查整套执行：疲劳、时间分配、注意力、紧张和题型切换。
This pattern often feels random, but it may actually mean the full-test routine is not stable yet. 这种波动看起来很随机，但可能说明整套考试流程还没有稳定。
Pattern 3: single tasks are fine, full tests drop 情况 3：单题会做，整套掉分
Doing 10 WFD sentences in isolation is different from doing WFD near the end of a full test. 单独做 10 道 WFD，和在整套考试最后做 WFD，难度是不一样的。
You may need endurance practice, partial mock tests and better recovery between sections. 这时需要练耐力、半套模考，以及题型之间的状态恢复。
Keep a fluctuation record 做一个波动记录表
After each mock test, record section scores, abnormal tasks, execution state, error types and one variable to change next time. 每次模考后，记录分项成绩、异常题型、执行状态、错误类型，以及下一次只改的一个变量。
Do not change five things at once. If you do, you will not know what actually affected the next score. 不要一次改五个东西。否则下一次分数变化时，你不知道到底哪个因素起了作用。
Before booking the next test 下一次报名之前
Look for four kinds of evidence: diagnosis, ability improvement, stable practice scores and better test execution. 先看四项证据：诊断证据、能力改善证据、稳定练习证据和执行改善证据。
This is not an official booking rule. It is a practical way to avoid repeating the same expensive experiment. 这不是官方报名规则，而是一个更理性的备考判断，避免昂贵地重复同一次实验。
