The time the homework is performed is always different .It depents on several circumstances:such as difficulty of tasks or its quantity.The subject that i usually start with is Math.I do so because i believe that it is easier to start with hard subject and end with lighter one.About homework,indubitably,it is necessary, because of it we revise material and eliminate misunderstandings.But ,as it oftenly happens , quantity of homework is not always considers interests of pupils.They are forced to learn big poems by hard or to read 100-200 pages for a few days.Interest and after school activities are not considered, so children sometimes don`t have enough free time , they even do not have enough time to sleep.So ,as for me , there should be less homework , but if pupil want ,he can take more.But it is only my opinion
