When you answer the questions sequentially, you get 20 percent partial credit for answering the first question correctly, 30 percent for answering the second question correctly, and 50 percent for answering the third question correctly.

If you answer the third question correctly and leave the first two answers blank, you receive 100 percent credit. If you answer the third question correctly but either of the first two answers are incorrect, you will only receive partial credit.
