Dear aspirant !

Hope you are doing great ! I know you are asking for yourself by just taking the name of your friend, don't worry i will help you . See, CBSE conducts compartment exam for those students who have flunked in one or two subjects during their 10th and 12th . These exams are conducted immediately after the CBSE announces its 10th and 12th Board in June or July . So don't worry , work hard in future . You are able to give compartment of two exams but not more than that .

Hope it helps you !

Thanks
