when will class 11 and 9 results arrive and how
Hello aspirant,
Class 11th and Class 9th exams results are declared autonomously by schools. Every school has their own academic calendar and result declaration date. But since due to covid-19 the schools are shut, therefore there's a delay in declaration of the result. You can expect the declaration of your results once the lockdown is over. also for more clarity I'll suggest you to contact your school administration.
Good Luck
