Hi Hinata!

Contact CBSE immediately by approaching the customer care/helpline department via phone, mobile, email, etc.

Hope this answers your question!

• According to the CBSE NEET Information Bulletin Chapter 4, Clause 7 it is mandatory for the candidate to bring an additional passport size photograph indicating clearly the name of candidate alongwith the date of taking the photograph for affixing it on the specific space in the attendance sheet on the day of examination.
  

• In my opinion, they won't be any problem with regards to the photo. However, just to be absolutely safe. Carry the same photo that you uploaded on the form as well as ask the Photographer to change the background color and affix your name and date.

• These are just precautions and you need not worry about anything. Just focus on your preparations now and give it your best shot! All the very best for your preparations!
