There are definitely areas of the American school system which are a bit weird, even from our own perspective. For example, the system at college means that you have to gain a certain number of credits in order to graduate. Each class is assigned a number of credits, usually depending on how hard it is.
You can’t graduate without the required number of credits, and sometimes the math doesn’t add up. This can result in a bizarre situation where, like this girl, you are 0.5 credits short and can actually graduate by taking an 8-week bowling class. Who knew you could minor in hitting pins.
