Yes, as a student who passed in 5 subjects in the 12th CBSE board exams in 2024 but got 'Repeat Theory' (RT) in the 6th subject, you are eligible to appear for the compartment exam in that one subject in 2025 .

According to CBSE rules, students who fail in one or two subjects are placed in the compartment category and are given a chance to clear these subjects in subsequent examinations. You are allowed a total of three attempts to clear the compartment exam.

Since you did not appear for the compartment exam in 2024, you can avail the subsequent chances. The compartment exams are typically held in July/August of the following year. Therefore, you should be able to appear for the compartment exam in your failed subject in July/August 2025 .

Here's what you need to do:

• Stay in touch with your school: The application process for the compartment exam is usually facilitated through your school for regular students. They will likely inform you about the dates and the procedure for applying.
• Check the official CBSE website: Keep an eye on the official CBSE website ( https://www.cbse.gov.in/ ) for notifications regarding the compartment exams, including the schedule and application dates.
• Fill the application form: You will need to fill out the compartment exam application form and pay the required fee. Your school will guide you through this process.
• Prepare for the exam: Focus on the subject you have to reappear for and prepare well to clear it in this attempt.

This July/August 2025 session will likely be your second chance to clear this subject (the first chance being the compartment exams held in 2024 that you didn't take). You will have one more chance after this, which would be the compartment exams held in the July/August session after the annual board exams in March/April 2026.

Make sure to contact your school administration to get the exact details about the application process and dates for the 2025 compartment exams.

I hope this helps.
