What does he mean?

[Latoof]

Hi everyone,
My teacher wrote a comment on my research, which I really would like to know what it means. The comment was as follow:
"A spirited attempt to construct an argument which befits a veritable devil's advocate."
I know what is a devil advocate, however, I want to know what does this sentence mean in general.
Thanks in advance,
Latoof

You probably meant an excellent student. Your teacher did- a spirited effort is a good, keem, lively one.

Yes, I meant that I am an excellent student however, ment is good. One more thing, I did all the work, he did not do anything for me. He just put the mark and underlined the mistakes, if there were some.
