From Guido @slack

programming assignment which asks for a recursive implementation

1) student A passes 10/10 tests, but uses a for loop: grade 1.0
2) student B passes 1/10 tests and uses recursion: 1.0
3) student C passes 7/10 tests and uses recursion: 7.0

there is no way to model this with the current check lists

if the checklists have a low weight, student A scores too high

if the checklists have a high weight, student B scores too high

basically, you want checklists for penalties

This support is added by having Addition Grades which can have a bonus weight with support for negative weight (penalty).
