# This program prints an intro message describing what the program does,
# promts the user for three quiz scores for the first three quizzesand then
# prints out the final quiz percentage (which is always comprised of the
# highest score for each quiz). 

# NOTE: this program does not compute quiz scores the way they will be computed
#       in your grade. We will improve it later this week to compute your quiz
#       scores correctly

    # if each quiz is out of 10 then the overall percent is the total points
    # over points possible (30) multiplied by 100 to make it a percent
    percent = counter / 30 * 100
