Most high schools and some colleges are based on a 16/17-week semester system.
Students from these schools find it very difficult to adjust to the fast pace of the 10/11-week quarter system. Understand that due to the short amount of time, professors tend to cram a lot of information in a little space. The same amount of stuff that ususally happens in a 16 week course now takes place over a 10 week period.
On a quarter system not keeping up with the work and completing all of the necessary readings can set up up for failure because everything happens so quickly. Once you fall behind in the quarter system, it is very difficult to make up for lost time. Midterms can start as early as the third week and appear as late as the eighth week.
My daughter attends a school on the quarter system. Classes are held on a 10 week cycle that began on Jan 4 and will end on march 8 . There are with 2 sets of midterms: first send betwen last week of Jan and first week of feb and second set about 3rd week in feb. Final week is held after classes end from March 11-15.
I think as with anything it is about making the adjustment.
