So unless Sally is indeed as thick as pig shit and had to resit GenEd she's unlikely to be the cheater.
Unlikely, she said she's taking science for STEM credits, so it's likely she's already passed her gen ed classes. But her not being very good with formulas, math or even understanding the scientific theory that Willcock (

) was teaching is an indication that she is the opposite of Derek when it comes to academics. She actually needs tutoring whereas Derek is more likely to tutor someone instead. (If he ever wanted to make serious amounts of money ofc)
Actually quite interested to find out how things will work out between MC & Sally.
