The rescaled mean of the midterm was 73. The overall distribution looked like this:

The exact number circled at the top of your exam is what I have recorded. It will be added in with up to 50 points from your problem sets, up to 50 points from your project and about 136 points from your final exam. If I was assigning letter grades today, based only on your midterm, they would look something like this:

85+ is in the A range

70+ is in the B range

60+ is in the C range

50+ is in the D range

< 50 is an E
