Verbal section - first and last questions

I have given 4 mock tests so far. In none of these tests I had 1st question, in-fact first 4-5 questions, as RC. Is that normal?

Moreover, last 3-4 questions have never been an RC.

Is that normal? Is that something I can count on? Has anybody seen an RC as his first 4 or last 3 questions?

The reason I ask is beacuse as the verbal section starts it takes me 2-3 questions to get into the rhythm and, moreover, towards the end I am sorta rushing. Does GMAT understand such scenarios and try to make test takers life a bit easy by deliberately starting off and closing in with kind of questions that one can answer in less time? Or is it just a mere coincidence for me? Maybe because I have never score very high in Verbal and GMAT knows that I am sucker so gives me easier of the options :p ?

Thanks.
