But I’ve seen a lot of students get a B because some other students did such outstanding projects it makes just checking off the items on the rubric look average. I guess it is up to a teacher to decide whether everyone gets an A or only those who got 100% on everything.
Homeschooling has the advantage of moving at that student’s pace, of scheduling tests or other evaluations at the best times for that student, of repeating work until it is mastered (which is a great thing). It’s up to the parent to set the rules.
