Final Grades

I calculated the grades as follows. The scale that I like to map grades onto is the below. Note, I cannot give A+'s on the grade sheets, but if your final grade is above 94, give yourself a pat on the back! You deserve an A+.

94 - 100: A+
87.5 - 94: A
84 - 87.5: B+
75 - 82: B
70 - 75: C+
62 - 70: C
52 - 62: D
Below 52: F

So, I did the following. For the labs, I divided the lab grades by 10 to get a lab score out of 100. This was then multiplied by .55 so that labs are 55 percent of the final grade.

For the midterm, I used the following awk script to convert the midterm score into one out of 100. Your score is i:

  top = 34
  a = 29
  b = 24
  c = 21
  d = 16
  if (i >= a) {
    score = ((i-a)/(top-a)*12.5+87.5);
  } else if (i >= b) {
    score = ((i-b)/(a-b)*12.5+75);
  } else if (i >= c) {
    score = ((i-c)/(b-c)*13+62);
  } else if (i >= d) {
    score = ((i-d)/(c-d)*12+50);
  } else {
    score = (i/(d)*50);
  }
  printf "Question Midterm : %.2f / 20\n", score*.20
  printf "  Actual midterm grade (out of 38): %.1f   Out of 100: %.1f\n", \
         i, score
}

On the final, same algorithm, starting with:

  top = 40
  a = 32
  b = 24
  c = 17
  d = 13

The midterm is then multiplied by .20 and the final by .25, and your scores for the lab, midterm and final are summed to get a number out of 100. Your grade is then assigned using the scale above.
