<p>I’d try negotiating for the full 300 points.</p>
<p>I don’t know if this applies to most majors or colleges, but at least in the classes in my major (an engineering one), the usual policy is to extend the grade of the next exam if someone misses an exam.</p>
<p>I happen to get myself into situations where I’ve had to legitimately miss several midterms, and what I noticed is that every single time, when I had to get that extension, the instructor always changes the policy to one where if someone did better on the final than on the midterm, then the midterm grade gets replaced with the final. In the majority of the cases, the instructor openly states that he doesn’t care about the excuse. </p>
<p>In any case, I’d argue for the full replacement, as it requires no real additional effort on the prof’s side, while it still allows for a fair assessment on how well you understand the material. I personally would argue that giving a 0 on the midterm is unfair because even though it is your fault, the 0 does not represent how well you understand the concepts of the class if you missed it purely by oversleeping.</p>
