Answer:祝你在考试中取得好成绩。 Ping Yin: zhu ni zai kao shi zhong qu de hao cheng ji

good luck means "hao yun qi"好运气 but we don't use "hao yun qi"好运气 whe we say something before a friend go have a exam.We usually say "祝你考试取得好成绩！"means wish him get a good grades I think it's the same,because the good grades are the result of the good luck! I think even we say in different way but mean same thing.

祝你马到成功！
