Thank you. I think my version is called a mixed condtionl with present-time implications, whereas Mr. M's correctional effort could be called a type 3 conditional.
My original writing, I believe, dealt with a person about to graduate from middle schoo. I think I wrote how wonderful it was, the teachers and students included. Then, I thought about Sue, then came to this:
Mr. M's correction:
I remember Sue, who transferred to another school just two months before this graduation date. Had she stayed in our school , she would have been expecting to graduate in a month like me.
My orginal sentences:
I remember Sue, who transferred to another school just two months before this graduation date. Had she stayed in our school , she would be expecting to graduate in a month like me.
I feel my version is OK, possibly better, since it carries a present-day implication as a mixed conditional, like "If I had studied harder at high school, I would be expecting to a good college now."
