Academic Language Week 32 - Exit Exam

Should a student have to pass a high school exit exam to earn a high school diploma?

I think students should have to obtain a high school exam to earn a high school diploma because that way they can remember everything they have learned during their past four years in high school.  I think each test is better when it varies each year because most things we learn we forget.  I think students should obtain to pass a high school exam because it motivates the students throughout all 4 years letting them know that they have to pass a test in order to get a diploma.
