Hi Aspirant,

Hope you are doing great as per the question asked by you, if you fail in physics in class 12th then you will come under compartment as you have to give the paper or exam again to pass as if you are not able to pass the exam then you will certainly fail it. So you are advised to work hard to pass exam in one go only so that you does not have to give exam again.

Hope you found this answer useful.Stay motivated stay positive.

All the best!
