umm... so in one of the previous questions the system did not accept "went", only "was going to", now it accepts both. these are different tenses, aren't they? (one is simple past in English, the other I can't remember - it has been a while since I've learnt English grammar, sorry)
"Would" can be used in the same way as "used to" for habitual actions in the past, rather than as a conditional. I think it's a bit of a stretch in this case, but technically it works.
For example: "When she was a student, every Thursday after lunch she'd go to the library to read a magazine." It really needs some context, though.
This sounds like "she was going to read a magazine, but she decided to do something else" instead of just an event that happened in the past like saying "she read a magazine". I understand that PC and imparfait are difficult to distinguish for English speakers, but this is a bad example that doesn't help demonstrate it.
