We all face problems in life and at some course time it get resolve.But while facing initially almost all problem seems like difficult but when it resolve we get that it was very easy to handle them.So we all are experience with solving real life problem.
Same happens during studies, when we start every academic year we found subjects difficult enough but when we done with it.we found it little easier than it was.
A student can easily help a student there in lower class to him.So students can help each other by making a self help group for studies.
Great opportunities to help others seldom come, but small ones surround us every day.
