appreciate advice regarding the PASS testing tomorrow

I gave my son (2 mths. shy of 10) the placement test for the PASS test. Tomorrow I”m going to give him one out of three of the regular tests. Each section had 12 questions and you subtract the amt. they get wrong from the 12 and that gives the level they should test at in the booklets. He got 11 correct on Reading, 10 in MAth and 11 in LAnguage Arts and that is your starting point on where to place him as they should get 50-90% correct on the test itself.

I’ve decided to definitely go up a level on the reading-I knew that would come easy. I’m surprised on the MAth, and I know he took the longest on it because we use Developmental Mathematics and it follows a different scope and sequence, so he hadn’t been directly taught some things but he has a foundation in thinking mathematically, so I guess that’s why he did better than I expected, but it was a challenge, but he still only missed 2. So, my husband wants me to test him at a higher level on everything so he won’t get bored or lazy (like our oldest di, but he was in “the system”, but I get it out getting lazy brained if things come too easy; but I’m hesitant about the math. I think it should be  challenge, but not be overly frustrating-I know what he hasn’t “learned” yet. So I’m stumped on whether to go up on him in MAth and the same with LAnguage Arts. I was surprised at him only missing 1, but several of them exasperated him, which is fine when there’s only 12 questions, but the regular test has many more, but it’s not timed.

 So should I go up one there too; even though we have been very leisurely regarding LA in our PLL? This is my 1st time doing this and I may be overly thinking this. Thanks for your advice.
