<p>Thank you for all your thoughts.
The school is still open to letting him do whatever we think is appropriate, but, A BIG but…
Since I first posted this threat, both P and VP have been after me, trying to make me realize that by pushing him forward I am not making him smartert or better educated. VP, who usd to teach science for many years, had this long talk with me yesterday about the 7th grade science curriculum and how important it is as a ground knowledge for all the other sciences S will ever take in his life. I agreed, saying that however the whole material is presented in kind of a simplistic way and that S, and school is aware of that as they were the ones administering the tests, tops their results both in Math and LA and is therefore more than ready for a more advance way of instruction.</p>
<p>I checked with HS, they do not know that if he would be getting a credit or not, more likely not, but they were kind of willing to put him in Bio class (the going sequence for learning science here is the same as presented by Marite).
The Bio however is in the worst possible period for S, so I am thinking that for now we are going to be quiet and let him do just regular 7th grade work, possibly with some supplementation by the teacher. I hate to be the pushy mom 
Makes me sad though, that the school has tons of people and tons of programs designed to help learning disabled who are struggling and lagging way behind in their results. My S is also “learning disabled” but in the other way - he is in the top 1/2% of the population for his age and he also needs a differentiated instruction and curriculum in order to progress. However for kids “disabled” the way my son is, there is absolutely no money. But I am touching on a totally different subject here…</p>
