Just curious. For example, if a teacher put a grade in incorrectly could they change it after the term is over? Could they after the year is over? I use infinite campus btw.
If they genuinely made a mistake, I would imagine it could be fixed, but that is probably more of a question for your school’s administration. See the teacher/guidance councilor, as every school has different policies.
This happened at our school a couple of times, sometimes the when the teacher submits the grades the administration messes up and might put the wrong grade what we do is we go to our counselors and they help us with changing it, but our teachers have to sign a paper for approval. This really changes from school to school so you would have to check with your counselor.
