What would be 'from the school'?
The very same thing!
college not accepted... should it be?
College = faculdade.
That's not strictly true - in UK, "college" can also be for pre-degree education, similar to school. (e.g. "6th form college" where students study for A-levels).
"colégio = high school" was accepted.
For this tense, would the past tense of "ter" work here. For ex, can it be "eu tive ido?" tô mean "I had gone" instead of "tinha ido"?
No, in this case you have to use "tinha, tinha, tínhamos, tinham".
