I passed CBSE 12th in 2017. Can I give an ISC exam now?

Hey Kaustuv,

Here is the criteria for appearing an ISC exam:

Students can be admitted to Class XI in the schools affiliated to ISC board only if they have cleared the ICSE exam or an equivalent Class 10 board exam with five subjects, including English.
Students can appear for ISC exams only of they have at least 75% attendance in school inClass 11 and 12 by January 31of the corresponding academic year.Anyhow, the Chief Executive and Secretary may allow the students with 60% attendance and above in special circumstances like prolonged illness.
There is no specified age limit for the exam.

Hope this helps,

Thank You.
