Current Events In Our School (continued)

EXAMS
The common exams start next week. My problem with the common exams is that all of the "important" exams are in the same week. For example two weeks from now, on monday we have history and physics exams, on tuesday biology and on thursday german exam. These are the hardest exams for many students in our school including me. It doesn't make any sense to put them all in the same week. First of all he biology exam always has to be on a monday because it takes the most time to study. Secondly, physics and history should never be on the same day because they also take up a lot of time study for. The exams should be spread out into three or four weeks so that we can study for them properly.
LATES
There is a 5 minute break between most of the lessons. The distance between the classrooms is huge. There are A,B,E and F blocks. Each block has 3 floors. So I'm not going to say impossible, but it's really really hard to get from one classroom to another. That is why we are late for classes many many times. However it's not like we are 10 minutes late or anything. It's mostly less than one minute, but our teachers write us as late anyway. It's not our fault that we are late. So either the breaks should be longer, or the late system should be changed. I will give an example. On fridays our first two lessons are math. Then, we have a 10 minute break. Third and fourth lessons are English. Math lesson is on A block 3rd floor. English is on E block 2nd floor. Our math book weighs like 10kg, so it's impossible to carry both math and english materials at the same time without fainting. Also since I get hungry by the third lesson, I have to buy a toast from the canteen. So in ten minutes I have to go down 3 floors, go to my locker, put back by math materials and take english my stuff, go to the canteen, wait in the line, pay the money for the toast, buy the toast, go up 2 floors and make it in time for the english lesson. Can somebody please tell me how is that possible!!!
