Mrunal, you haven't mentioned when you made these changes and if NTA has notified about regarding making the changes to the Passport Photograph. Your Photograph should be atleast between a size of 10kb and 200kb with JPG format and 2.5*3.5 inches with 72 DPI. Now your face should also be 80% clear and ears should be visible. If this holds the case with your uploaded Photograph, then you are fine and you needn't upload another Passport size photo. But if you feel that the photograph is not clear, then we would suggest you to make the changes. And the last date for making corrections to the NEET application form is July 15th and so you may have to hurry. If you are changing the Passport Photograph, make sure to take the print out of the confirmation page for your future reference. And if you are preparing for NEET, you may as well try our NEET Knockout package: https://learn.careers360.com/knockout-neet-may/ .
