Extra Credit for Escape Academy 2: Back 2 School
24 optional headings, from Shelf Destruction to Montecluema's Revenge.
Extra Credit sits beside the 50 story classes. The walkthrough order has 24 headings, and every heading belongs to one group: optional. Three Steam honors track the list: the first heading you finish, a run of 10, and the full set.

The honors are counts, not extra room names. A Little Something Extra is the common one. This Should Help my Grades is the middle bar. Escape-a-holic is the rare one.
Elective register
Read the register from top to bottom. One group head covers all 24 rows. Each row is a heading plus its order number, and the name opens that heading. Shelf Destruction is order 1. Throwing Shade is order 10. Montecluema's Revenge is order 24.
There is no chapter split here. Story classes are grouped into chapters 1 through 8. Extra Credit stays a single sequence, which is why the register uses one group head instead of eight blocks. At 24 rows the order number is the locator: a heading's place in the chain is the number beside it.
Global unlocks on the three honors are 90.2 percent, 25.9 percent, and 1.0 percent. Most players have finished one optional heading. About a quarter have finished ten. Almost nobody has finished all 24. That gap is the useful read before you treat the list as required homework.
Each heading page carries the order, the optional group, and the next heading in the walkthrough chain. The last heading points back at Shelf Destruction. Puzzle steps for a single room are not copied into this register. When you need the story rooms instead, use the curriculum.
