My little borther and parents have moved to Bahrain, my brother has been enrolled into a British School doing the AS and A levels. However the problem he is facing is that after having done his school certificate here in Sydney is whether or not he should repeat year 10 and do the IGCSE's (O levels) in the school or go striaght into Year 11 and do AS and then A levels the nex year. He will be coming back to Sydney to go to Uni however if he DOESNT do the IGCSE (O levels) and does his AS and A levels will he still be able to apply and get into Uni based purely on AS and A level results without his IGCSE's (O levels)?
