I just thought I'd offer you a little encouragement - my son is in 7th grade now and progressing through Saxon 87, right where I had hoped he would be. He is not strong in math, as my daughter is, but does above average with all other subjects.
I began home schooling him in 4th. Ultimately - I decided that he'd missed too much of the basics in school. (He was excelling because many in his class were struggling with very basic addition, and in 2nd grade at the end of the year, over 1/2 the class had not passed the 1+ facts. That was when I started to realize his school was not going to help him achieve his goals. He got a wonderful teacher for 3rd and I spent the entire year seeking other alternatives & decided to homeschool.)
After his placement test - he tested possibly in 2B and maybe 3A - I finally decided to back him up all the way through 2A and just move quickly through anything he was doing well - to ensure he'd really grasped the basics.
This was not always easy - we had to do math in the summers, but not the entire summer, and we had to do 2 lessons a day for several years. However - he moved from 2A - 5B, even breaking off a while to do Life of Fred Fractions when he got stuck on those. He finished 5B by 6th grade, and began Saxon 87 in 7th.
It can be done! No worries - just pray before you begin math each day - and keep God close as you work! I need Him so much when I teach my son - who still does NOT love math! However, he is doing fine - and is usually scores a mid-B on most of his lessons, sometimes higher.
