I have mentioned my dob incorrectly in kcet and will they allow me to write the exam

Hello student its difficult because DOB is very important for any entrance examination that's depend on the examiner or authorities who will check your details at the of entry in the examination centre but even if you'll appear in the entrance examination you might face difficulties at the time of counselling for admission in respective colleges.

Feel free to comment if you if you have any doubt
Good luck
