A 4-minute challenge, 8 blanks. Listen to a short lecture and complete the notes just like in Section 4 of the real exam, only one listen allowed.
Tips before you listen
Watch for figures that sit close together (12% and 15%), a "desired" number versus the real one, and a synonym repeated from the notes that can hide an exclusion right before it ("not the refrigerator, but the water heater").
