is it really better to give than to receive?

I can't talk in general. But in my case you mentioned about examinations. I feel until and unless you don't help others they are not going to help you. During examination we friends always used to help each other. It's also funny. To get something you also need to give something in return.

hi sjermaine,
Nothing can give easily.
There are some cases that we should consider before we give.
Example, if someone ask you help to be a traffic illicit that illegal to country.
Then we do what they want.
that's are fool.
Think wisely is the best and you said is true.
Give whenever got help.

Regards.
