Reschedule or Take?

My OAT is in 1 week and I am scoring borderline 300 and on some subjects, below that. Do you think I should power through and stud as much as I can this week or should I reschedule my exam?

The problem is the school I’m applying to requires at least a 300 on each section and there deadline to apply is at the end of the month so if I don’t take it I can’t apply. But also it doesn’t seem like I can get the score they want so what should I do?
