<p>I agree with the consensus here of staying in touch with your math teacher and getting to your GC or vice-princ. asap. And I actually think that Corroborator may be touching on one good point which is, what happened to the other students who went on the trip to France? It might make sense for you to be in touch with them as it is possible that some of them are in a similar situation and that they or their parents might already be working on a solution with the teachers in question or school administrators. Particularly if they have parents who are amenable to being involved and helpful, it might be good for you to work together toward a solution that benefits all of the students involved. (Also, if any of those students has already acheived some measure of success in dealing with the situation, say with a different guidance counselor or teacher, it would be great for you to know about.)</p>
