<p>I would not worry yet. I was in the same position a few years ago. I came from the advanced IGCSE system in Zimbabwe to a far inferior curriculum in SA. For two years, I did nothing and scored low B’s. In my last two years though, I realised that I needed the grades. I did not work ‘hard’ but just hard enough, even in the classes I didn’t like to give me a shot a HYP (Which I am anxiously waiting for now). Like your son, I was nationally ranked in Science and Maths, but also English. My point here is that, as the work becomes harder, his marks will improve because it will begin to interest him, and college will become an immediate reality.</p>
