I would mention that they could always un-honors him in science at the end of the first 9 weeks or at the progress report time (ours is 4.5 weeks into school) if your son doesn't perform but to under-place him will certainly not spark him to rise to the occasion as evidenced by last year's placement. And if they place him regular science and not honors science if he gets 100% on every single assignment and test are they going to consider changing his class up---NO...he would have missed that boat and would be behind the honors group. You can always go down but you can bet they don't tend to move you up.
