Hello dear aspirant.

Actually if you don't tell them then also they will be known to this fact also actually they have gone through your resume and profile in very detail.

As if you tell them about all these things then you will be also ready for few other questions like why so and all such.

Hope you get it.

Good luck

Dear Albert, it doesn't really matter how many times you have attempted your 12th. The end result is what that matters. You are being honest. But you should be smart when answering questions. If the Interviewer asks you how many attempts you have taken to complete your 12th, then you can answer. But without them asking you, you needn't proactively answer. You are not lying or hiding anything. You are answering the questions they have asked you. Answer and reveal if asked. We sincerely doubt if anyone would ask such a question.
