Ironically, my husband is a teacher and tutors many kids in algebra! As SwimmingDad said, he makes a fortune tutoring kids in their honors/ap classes. Unfortunately, they 2 of them battle each other at every turn!!! Something she wouldn’t do with a “real” tutor - unfortunately the going rate in my area for a tutor is $85/hour - that just isn’t happening!
My son actually did algebra 1 over, online, the summer before taking Algebra 2 and it really helped. She would also be much more receptive to that because she is very concerned with keeping her grades up.
A lot of her problem was (and is) test panic - she understands the homework, goes for all the extra help sessions and gets it, then just doesn’t do well on the test.
