What are the effects of frustration on the academic performance of a student?

A student who is frustrated will easily give up on whatever task he or she is involved with because they feel that it is a stressor, therefore it will cause them more stress trying to work on something while thinking about the subject that is the source of their stress and frustration. Thus, they won't want to work on an assignment, for example, because they're not focused and are stressed since they have something else on their mind.
