Comparison of education between Iran and Canada

Actually they are compeletly different and and both of them are following two seperate ways.In Canada you can choose lots of course which are not depending on each other.I mean you can choose math with history together which are not talking about the same subject but in Iran you have three choices math,science and art and each choices are following just certain subjects for examplie if you want to study in science you do not have to pass something like math 12 but you have to pass science 12 and you can not take history or philosiphy becouse these courses belong to art although by this methods you have to decide about your future when you are just 15 years old (Before you want to go to high school) !sound is funny but that is fact,If you want to be a doctor you have to take science or you want to be engineer take math and take art if you want to be psychologist and when you choose one of them there is no turning back,Actually there is but it will kill you if you want to do this.Some rules in Canada are soft however in Iran some of them are very like times of attending in the class are very earlier or bringing mobiles or ipads in the classes are forbiden and even drinks.
