I found them by accident this morning and I'm in a state of shock. We'd talked about it before and I'd explained the dangers of buying things over the internet but obviously he's gone ahead and ordered them. He's of the opinion that he's at a disadvantage if he doesn't take them, 75% of last years Cambridge students admit to taking them, etc. I just don't know what's true and what I should say when he comes home from school. Any advice would be greatly appreciated.
