會考Oral試場可唔可以影相?

試場範圍內一定唔可以開手機,

影相? 唔係呀ma? 仲咁有心情?

不如預備下仲好la...
係咪?

Do you mean to capture the scene of your whole interview process? If yes, then I think it should be not possible. But you still can ask the teacher for doing this.
Remember that nothing is impossible, but you should communicate with the authority before any doings.

And I think this will make you much more nervous during the examination and also after the exam.
