Difference in meaning:
- "I wouldn't make it "
- "I didn't make it"
where using the first phrase to express something that wasn't done instead of the second phrase confuses me.
A month ago, I knew I wouldn't make it to class yesterday, because I had a doctor's appointment scheduled.
I did not make it to class yesterday because I had to see the doctor.
The first, with wouldn't, refers to the future relative to a point in time in the past.
The second, with did not make it, is simple past, referring to what happened (or did not happen) in the past.
