w: I saw you at the visiting scholar's lecture yesterday. I didn't know you are interesting in behavior modification.

m: I am not but my psychology professor gives us extra credit for going,and I really need it.

a) he is not doing well in his psychology class.

b) he needs information about the behavior modification.

答案：a

我的问题：  extra credit assignment 是给学习成绩好的学生的荣誉加分，还是给差的学生的补分？

总之是加分，而且m REALLY 需要它

呵呵，这个跟国外学校的学分制度有关系，如果修不够学分不给毕业，所以m需要学分。而有时就开一些好那学分的其他专业选修课。所以这里是应该是a.
