My son was diagnosed with chronic disease last year and although his grades are not bad he is sometimes unable to attend school or exam from the reasons beyond him. We just heard that he could disclose the chronic disease as a "mitigating circumstances" when applying to Uni. He already applied but still not heard from 3 unis so he could still update his application. We are a bit scared and we think that it might disadvantage him instead of endorsing. Anybody has any experience in that area maybe ?
