Reading Comprehension

Does anyone know if the questions on a RC passage follow any particualr order? I mean, if the passage consists of 4 paragraphs, can the first question ask something speicifc to 3rd para and the 2nd question tests something about the 1st para etc? Or, would they normally testing the paragraphs in the RC in an ascending order(ofcorse ignoring "primary puprose" related questions).

Appreciaet anyones insight on this.

i wonder how knowing that will help..

first of all.. there is no rule that each RC will have a fixed length.. moreover i know few ppl who hav taken GMAT, few of them in the same time slot, on the same day n still get different RCs - of different lengths and also the no of RCs vary..

i think one shud concentrate on on concentrating while reading the passage than formulating weird rules..
