Yes, you can definitely give the Chemistry exam again along with the other 4 subjects as a private candidate next year. Here's why:

• Private Candidate Flexibility: As a private candidate, you have the option to choose specific subjects you want to reappear for in the CBSE board exams.

• Previous Attempt Doesn't Affect: Your performance in the July improvement exam won't affect your chance to retake Chemistry next year. The best score out of all your attempts will be considered for the final result.

Here's what you'll need to do:

• Apply During Registration: During the application window for private candidates next year, ensure you select Chemistry along with the other 4 subjects you wish to reappear for.

• Check Subject Availability: In rare cases, some schools might not offer all subjects for private candidates. Double-check with your chosen exam center to confirm Chemistry availability.

By following these steps, you can retake Chemistry along with the other subjects and aim for a better score next year.

hope this helps you!!
