    • Spot repeated topics.

    • Give importance to chapters from NCERT books.

    Dear Student,

    During NEET UG Counselling, a character certificate is generally considered valid for only 6 months to 1 year from the date of issue. Since you are taking a drop year for NEET 2027, your school-issued certificate will be expired by the time you reach counselling.
