Wesley College IB Program

I am new to Melbourne and would like an honest and reasoned opinion about the IB program at Wesley College in Melbourne. My son is about to enter year 11 there and he's used to an international education as we've lived in many countries. Of course, we want the best education for him and potential opportunities for his university choices overseas, and we wanted co-ed. I'm hoping we've made the right choice but we didn't have too many options as we had to get him in quickly. Advice much appreciated
