Hello there,

In the HSC Physics exam, if you did not fully write the answers to the MCQs but mentioned the option numbers (like A, B, C, etc.), and the answers are correct, typically:

1. If the instructions clearly ask for only the option letter (A, B, C, etc.), and you have marked it correctly, you should not face any mark deduction.
   
   

2. However, if the instructions require you to write the full answer and you only mentioned the option letters, some examiners might not award full marks depending on how strictly the instructions are followed.

To be safe, always ensure to follow the exam instructions carefully. If it was just marking the correct option and it matches the answer key, you should get full marks for that question.

I hope this answer helps you. If you have more queries then feel free to share your questions with us we will be happy to assist you.

Thank you and wishing you all the best for your bright future.
