What kind of knowledge does Buddhism provide for their benefit?

My students often ask the question that when other school subjects they study provide them with various types of knowledge regarding managing the Four Basic Requisites in their everyday lives, then what kind of knowledge does Buddhism provide for their benefit?

Some students got low marks from the entrance exam, which constrained them to study in their less favored college. what should they do?

I would like to ask Luang Phaw about the college entrance examination of high school students. Some of my students were disappointed with the low marks they got from the exam, which deprived them of the chance to enter their chosen college. Then they were constrained to having to study in their less favored college. May Luang Phaw explain to me regarding what they should do?
