根据搜索结果，关于“你这次考试怎么样”的英语表达，综合整理如下：

二、注意事项

避免混淆

- 考试内容用 "the exam" 指代，而非 "exams"

情感表达

- 可以用 "nervous" 描述考前状态（如：I was very nervous.）

若想表达鼓励性建议，可用：Put yourself together, I'm sure we can get good marks.

考试类型不同，表达需调整，如口语用 "How was your English test going？"，书面语建议用 "How did you fare in the exam？"

建议根据具体考试场景选择表达，口语交流优先使用 How was your exam？，书面表达则需注意语法规范。
