"proof of my good English skills" or "proof for my good English skills" Hello! I need help from a native English speaker (British English). Does the following sentence sound good? My IELTS score also stands as proof of my good English skills. Or should it be: My IELTS score also stands as proof for my good English skills. If you think there's a better way of saying this, I would like to hear your suggestions. Thank you in advance.
