That pretty much how mine works. Midterms winter break-ish(basically just new year and Christmas are free) then exam weeks 2-3 of them depending on the semester.
For summer semester its a bit easier mid terms are first week of may some leak over in the following weekends till end of may. And than a week break and than exams. again 2 or 3 week duration. 

It doesnt help the case that where I am studying now every class has two exams one written(/practical) and the other spoken(/theory) which means two exam days instead of one per class

But I must admit that this system where things are separated, even thought it is more time consuming, does allow me to have higher grades, than when I didnt have double exams......................................

Ugh...I ranted *chuckles*...ah the common student illness,at least where I live, a student just cannot shut up about their studies, regladless off to who they are talking to XD
