Solo/Ensemble contests requires movements 1-2 or 2-3, but where does each movement end and the next begin?

I see the Andante (including Presto) as the first, the Allegro as the second, the Adagio as the third, and the Menuetto I and Menuetto II as the fourth movement. However, I've been told the Andante is the first, both the Allegro and Adagio are the second, and both Minuettos are the third. Which is it?

Also, any idea on tempos for these sections?

Thanks, J.
