This Course is equivalent to the Xth standard. You can choose subjects from the Scheme of Studeies given in Table-. However, you will be required to successfully complete a minimum of five subjects with atleast one language or atmost two languages, which is compulsory for certification

Of all the answer i conclude you that you will have to reappear for exams to select your desired career line. You will not loose your dignity by reappearing exams.
