Hello aspirant , hope you are doing good.

So , to answer your question, I'll say that it's always better to stick to the same passport size photograph that you have attached to the admit card, to be used for counseling as well because if you don't , it might cause you unnecessary trouble while the counseling procedure, because they might not accept a different photograph and you have to put in alot of effort to convince them. As you might be knowing, rules and regulations are very strict in NEET so it might be an issue.

Hope this helps you. Good Luck!!
