Help, with parts of speech

[ugp]

hello,

I have to look at a bit of language and label or name the parts of speech, for school. Can some one check that this is ok pleae?

It was pandemonium almost as soon as the roadworks went up.

Subject Pronoun (it) / verb (past simple of be) (was) / noun (pandemonium) / adjective (almost) / preposition (as)/ adjective (soon)/ preposition (as)/ article definitive (the) / noun (plural) (roadworks)/ verb + partical (phrasal verb) )went up.

It is about a man talking about a traffic jam. I hope the spelling is correct, if not I am sorry.

Thank you in advance.

Edit: Could the "as soon as" be classed as a complex preposition?
