I. How is Exam 2 scored?

35 mulitple choice questions x 2 points each = 70 points total

2 short answers x 15 points each = 30 points total

TOTAL EXAM 2 SCORE= 100 POINTS

if your GSI posts the Multiple choice scores as out of 35, you need to double your MC score first (so that it is out of 70), add that to your short answer score (out of 30) , to get your TOTAL SCORE (out of 100).
