to hold a grudge against someone

[Alexandro]

Hi everyone,

Can you say, when you notice somebody really doesn't like another person:

'He has something against her.'?

Can you say: 'I have nothing against that charity orginasation.'?

Can you say, when a student has bad marks for a teacher's classes:

'He holds a grudge against me for no reason at all.'?

Can you even ask him or her:

'I've noticed that you scored very well for all other subjects, except for mine. Have I done anything wrong at all?'.

Thanks
Alexandro

The sentences are okay. but in the context you describe your final sentence doesn't quite make sense.
It seems to me that the teacher wouldn't be accused of scoring other subjects well, but of scoring other students' work well.
