I am an international student and I have a problem concerning the School report that is supposed to be completed by a counselor. The problem is that my school does not have any counselor (or any corresponding person). What do you suggest me to do? Should I put a teacher instead of a counselor?
I have been also confused because in the School Official details, I have the choice to chose either a counselor or a teacher... so is it ok if I just choose the latter to complete my school report.
Finally, I have another question; our educational system is different from the US one. For example the courses that a student takes is the same for everybody and the level of the classes are the same. So what should I complete in the corresponding questions? Is there any place in the application where I can explain this situation?

Thank you
