Dear student,

If you have done some mistake in jee mains application form during filling, then you will be given a facility to correct your application form. The jee mains correction window will open on 19th january to 21st january 2021. So if you have image discrepancy, then you can correct it during that given period.

And if you don't upload your correct image then after jee mains it will create problematic situation to you during the counselling procedure and you may not be able to attend the jossa counseling.

So, it is advisable that you upload the correct image when the correction window opens.
