首先这句话里的in要去掉，英语里面不会有这种介词联用的（除非是动词短语）。另外good at的at是介词，后面的deal要加ing变成动名词。
以上是语法错误。
deal with的英文解释是：When you deal with something or someone that needs attention, you give your attention to them, and often solve a problem or make a decision concerning them.
所以a student（你） deal with a teacher is almost impossible.
你一个学生替老师解决烦恼忧愁甚至做决定是不太可能的，如果你要和老师打交道应该写：
Are you good at getting along with a teacher? 你擅长与老师相处吗？
