It is really pleasant that we get lots of questions about education. It shows that our little friends are interested in their studies.
We have already answered about getting higher marks in examinations or monthly tests. To secure higher marks you need to attend your classes and lectures regularly and complete your homework daily so that you could have a good preparation before the exams.
So complete your preparation before two weeks of exams and within these weeks just revise your work.
But the real purpose of education is to impart the civic sense so you become a good citizen. According to a Hadith of the Holy Prophet (peace be upon him) the acquisition of education is compulsory for every Muslim.
If you don’t learn to respect your parents and elders, behave with youngsters and poor’s means you didn’t get education.
