It can be either way since RTPCR not mandated so doctor certifying enough be it symptoms or disable or anything which make you not fit for exam or study
When the opt out window will be updated and there is any format would be given by ICAI for medical practitioner or medical practitioner can give his own, and that will work for opt out
Can I upload my rtpcr report which shows that I'm covid positive on 21st May.. is that enough for my opt out..or should I again go to a doctor for my post covid symptoms and get a report??pls help me out guys
