Dear Rachel

 You got 85 (out of 100) in the makeup exam

 
Here is what you got wrong:

#1: form the answer is wrong: -7 points

#2: wrong answer, right way (but WAY too complicated, hence you messed up): -5 points

#6: wrong ans. but RIGHT way (careless error): -3 points

Since this is higher than 20 (that you got in midterm 1) 
your score is 85

 Best wishes,

  Dr. Z.
