Hard work + dedication to me is a single subject, not compound.

All of your hard work and dedication has ..

Now if it had been
hard work and luck I would have went with compound subj.

Disclamer: I hated my 9th grade Grammar teacher, and it was certainly likewise.... I shut out a lot of lessons I should have mastered.

Answer 3

Well, Writeacher and I disagreed, but in general, you would be wise to trust Writeacher in these matters.

Answer 4

Well, actually, the subject is "All"

Is "All" singular or plural?

Answer 5

I'd decided that it was plural since "all" referred to two things -- hard work and dedication. But I backed off for the reasons that Bobpursley gave.

Answer 6

I disagree ... I see "hard work" and "dedication" as two different things.

It'll be up to Suzanne to decide!! =)

Answer 7

When I am trying to decide between 2 possible answers in a situation such as this, I say the sentences out loud. Which one sounds correct? This can help SOMETIMES... For instance: I ate an apple. OR I ate a apple. Say each one out loud... one sounds more reasonable compared to the other.
