The first example is from the BEGINNING to m 65. There are THREE groups. A and B are the top and middle, and the low group both sing the third (combined) line.

Oh Biology – PART 2 – this starts with the solos at m 66, then breaks into groups A, B, C and D.
THE FIRST SOLO is Savannah, then she joins all the A group
This is HANNAH for the Solo, who then joins the B group
Next is MARLEY’s solo, then all the C group
WELLS (Claire?) (David?) then the D group
THE LAST Oh Biology is the little bit at the end starting in m102 – just some set me frees.
