If you pass in all subjects except Physics in AHSEC, you will likely be considered as pass but will have to take a compartment exam in Physics. You will not need to retake the entire exam next year. The compartment exam allows you to retake only the failed subject.

Pass with Compartment:

AHSEC, like many other boards, has a provision for students to retake a subject if they fail in only one or a few subjects. This is the compartment exam.

Compartment Exam:

The compartment exam is typically held shortly after the main exams (usually in July). You can take the exam in the failed subject (Physics in this case).

No Need to Retake All Subjects:

You do not have to retake the entire exam the following year. You only need to focus on the Physics compartment exam.

Pass if you clear the Compartment:

If you pass the Physics compartment exam, you will be considered as having passed your overall 12th grade exams.

Repeating the Year:

If you fail the compartment exam, you may need to repeat the 12th grade the following year.

For a more accurate and definitive answer specific to your situation, it is always recommended to consult with your school authorities or AHSEC officials.
