Lab: grading a test

Sign in if you want this lab saved to your progress.

Grade the test

Three scores are in. Work out the average and turn it into a letter grade — the way a teacher's spreadsheet would.

Given for you: test1, test2, test3

Build:

  • average — the mean of the three scores, rounded to 1 decimal
  • grade — A for 90+, B for 80+, C for 70+, D for 60+, otherwise F

Print the average, then the grade, one per line.

The autograder reruns your program with different scores, so write the rules once and use variables — never the numbers 88, 92 and 79 directly.

Build it

Fill in the code, then run it. Every check has to pass for the lab to count.

Given for you

test1 = 88
test2 = 92
test3 = 79
