Punctuality

In the United States, if you are not on time for class, the professor might lower your grade but he/she will never forbid you to enter the classroom. You just go in as inconspicuously as possible and find yourself a seat somewhere at the back. In Bulgaria, however, you’d better be punctual. If you happen to be late, you have to politely ask the professor for permission to stay. He/she might welcome you to the classroom, tell you to leave or require you to stand throughout the lecture. Some professors even lock the door after the start of the class.
