If they were to SSA, then they would definitely work on the language independently over the summer. To SSA, their teacher would have to recommend it. They are basically getting A/A+ with minimal effort and the class is excruciatingly slow for DD who has been complaining all year. I actually am not really leaning in either direction but I kind of prefer that they both make the same decision. Of course, it will ultimately be up to them. I think DD really wants to do it while DS is ambivalent.
