Actually, he doesn't have problems with timed tests. The only reason he hasn't passed them all yet (he has one more subtraction test to go) is that with the holidays and other activities going on at school, they have skipped several weeks of taking them. He knows all his facts and when I have him practice them at home a few days a week, he always gets 100% correct. In fact, the only two subtraction tests (at the beginning) that he didn't get 100% on, he got 97% and 99%. So, clearly he has them mastered. They are just a road block to him getting the multiplication tests at school.
