<p>My kids' school system has comprehensive semester finals, but they count for only 25% of the semester grade. Only the semester grade appears on the student's transcript. Marking period grades and final exam grades do not.</p>
<p>This means that for students who received identical grades for the two marking periods that make up the semester, the final exam is close to meaningless. Every kid in the school system knows this.</p>
<p>For example, if the student has an A for both marking periods, an A, B, or C on the final will yield an A in the course. Anybody who was able to get an A both marking periods can usually get a C on the final unless he or she happens to be unconscious at the time. (My son, who had As both marking periods in a computer science course, neglected to notice that the final exam was printed back-to-back and therefore left out an entire page of the three-page exam. He got a C on the final and an A in the course. Similarly, my daughter, who had As both marking periods in physics, accidentally put the multiple choice portion of her physics final in the "Form II" pile when she had actually taken "Form I" of the test. She turned in the essay portion of the test correctly. She also got a C on the final and an A in the course. It's really, really hard to get less than a C on a final.)</p>
<p>If the student has a B for both marking periods, an A, B, C, or D on the final will yield a B for the course. In this instance, it is absurd to study.</p>
<p>The only time kids care about finals is when their two marking period grades differ. Then, the final is the tie-breaker. Thus, kids are constantly pressuring teachers toward the end of the second marking period of a semester to tell them their marking period grade so that they will know whether they should study intensively or not at all.</p>
<p>At the school my daughter attended, the administration recently created a policy that says that if a student is taking an AP exam for a course, that student need not take the second-semester final unless he or she wants to. Of course, only the few students who need the final as a tie-breaker take it. This pleases both the students, most of whom get to stay home and sleep instead of taking a meaningless test, and the teachers, who have fewer papers to grade.</p>
<p>None of this prepares kids for college, in my opinion. In college, finals usually count for a much larger proportion of the grade and are always meaningful.</p>
