Can a student purge grade twice for algebra 1 if take in 7th and 8th grade?

My one hesitation would be that that you'd want a very careful look at the reason for a "B", in this age of grade inflation. Late homework, careless errors, one of the remaining teachers who still "hold the line"? Or is the kid missing some fundamental concepts from pre-algebra that mean he's not really grasping algebra material? Math is very cumulative.
