Not a generalization Iran Esteghlal Iran- an OBSERVATION
Now I know I can't have EVERY professor from Iran and Israel, that is impossible, population of Iran 80,000,000 + population of Israel 6,000,000, several million teachers from both of those countries. However based on MY experiences, I take that back I had One good Iranian professor Dr Makshofi and he was a GOOD Accountant. I did not know much about accounting, I would meet with him in his office hours, tired after football practice. He would even give me some chai so I could stay up and focus. He took baby steps with me and did not belittle me so THERE ARE SOME good Iranooni professors however
1- If you don't know the subject, most Iranian professors won't teach you. I have spoken to people IN Iran about this subject they will have their 1 pet who understands everything, and they will focus their energy on their favorite. Jews overall are pretty fair professors, they value HARD WORK and will teach you, if you show them the respect that that deserve.
