Hello,

No, you cannot appear for Class 10 board exams without Class 9 registration.

Schools send student details to the board through Class 9 registration. This step is compulsory for CBSE, State Boards, and most other boards. Without this, the board will not generate your Class 10 registration or admit card.

If your Class 9 registration was not done, you must contact your school urgently. They may guide you on whether late registration or any special process is possible.

Hope it helps !
