Y es, you can register and participate in the counselling processes for both AIQ and State Quota simultaneously.

Think of it like having two separate pathways to get a medical seat. The AIQ counselling, conducted by the Medical Counselling Committee (MCC), covers 15% of the total MBBS seats in government medical colleges across India, as well as 100% of seats in central institutions, deemed universities, and other specified colleges. This quota is open to all eligible candidates from any state.



On the other hand, the State Quota counselling, conducted by the respective state authorities, covers the remaining 85% of seats in government medical colleges and all the seats in private medical colleges within that particular state. For these seats, there are usually domicile requirements, meaning you typically need to be a resident of that state to be eligible.




You can register for the AIQ counselling on the MCC website and also register for the State Quota counselling on the website of the counselling authority of the state where you are eligible. You'll need to keep track of the different schedules and processes for each.

However, there's a crucial point to remember. Once you are allotted a seat and you join that seat in either the AIQ or the State Quota, you will likely not be eligible to participate in further rounds of counselling for the other quota. The rules are designed to prevent seat blocking.

For example, if you get a seat in the first round of AIQ counselling and you decide to join that college, you will probably be out of contention for the subsequent rounds of State Quota counselling. Similarly, if you secure a seat in a state quota college and join, your chances of participating in further AIQ rounds might be restricted.

Therefore, while you can participate in both simultaneously in the initial stages, you need to make a conscious decision about which seat to accept if you get offers from both. Carefully consider your preferences and the rules of both counselling processes before making a commitment to a seat.

The National Testing Agency (NTA) has designated several centers for the NEET UG 2025 examination in Bhubaneswar, Odisha. When you fill out your NEET UG 2025 application form, you will be required to choose up to four preferred cities for your examination center.

Based on the information available, Bhubaneswar is indeed one of the designated cities for NEET UG 2025 in Odisha, with the center code 3604 .

However, the exact address or name of the specific examination venue within Bhubaneswar will be mentioned in your NEET UG 2025 admit card. The admit card for NEET UG 2025 was released on April 30, 2025, and it contains all the crucial details about your allotted exam center, including the complete address and reporting time.

Therefore, while Bhubaneswar is a confirmed city for NEET UG 2025, the precise name of the center where you will appear for the exam will be available on your individual admit card. After downloading your admit card from the official NTA NEET website (neet.nta.nic.in), you can find the specific name and address of your allocated center in Bhubaneswar.

It's advisable to check the location of your allotted center in advance to avoid any last-minute confusion on the day of the examination, which is scheduled for May 4, 2025.

The best and safest approach is to get a new photograph taken specifically according to the NEET guidelines. Ensure that the photo is recent, colored, has a white background, shows at least 80% of your face (including ears), and meets the size and format requirements mentioned in the official Information Bulletin. It's also preferable to have your name and the date of taking the photograph printed on it.



In conclusion, while technically you might be able to convert a blue background to white, it is a risky approach and not recommended. To avoid any potential issues with your NEET application, it is best to adhere strictly to the official photograph guidelines and submit a new photograph with a genuine white background. Always refer to the official NEET Information Bulletin for the most accurate and up-to-date instructions.

The intimation slip, also known as the Advance City Intimation Slip, was released on April 23, 2025, and it informed candidates about the city where their examination center would be located. This was to help you plan your travel in advance.

The more crucial document that you absolutely need to check and download is your NEET UG 2025 Admit Card. The admit card was released on April 30, 2025 , and it contains the exact name and address of your allocated examination center, along with other important details like your roll number, exam time, and instructions.

Here's what you should do now:

  1. Visit the Official NEET Website: Go to the official website of the National Testing Agency (NTA) NEET: neet.nta.nic.in .
  2. Look for the Admit Card Link: On the homepage, or under the "Candidate Activity" section, find the link that says "NEET UG 2025 Admit Card Download."
  3. Log In: You will need to enter your Application Number and Date of Birth to log in and access your admit card. You might also be asked for a security pin.
  4. Download and Print: Once you can view your admit card, carefully check all the details mentioned on it (your name, roll number, center details, etc.). Download the admit card and take at least two to three printouts on clear white paper. Ensure that all the information, including your photograph and signature, is clearly visible on the printouts.

The intimation slip was just for advance information about the city. The admit card is mandatory to carry to the examination hall on May 4, 2025. Without a printed copy of the admit card and a valid photo ID, you will likely not be allowed to enter the examination center.

o get accepted into AIIMS Guwahati under the ST(H) category through NEET UG, it's challenging to provide an exact mark as the cutoff varies each year. These cutoffs depend on several factors, including:

  • The difficulty level of the NEET UG exam that year.
  • The total number of candidates appearing for the exam.
  • The number of ST(H) category candidates.
  • The number of seats available in AIIMS Guwahati for the ST(H) category.
  • The overall performance of candidates in the ST(H) category.
  • The cutoff trends of previous years.

However, we can look at the previous year's data to get an idea of the rank required, which can then be correlated with marks.

According to the NEET UG cutoff 2024 data, the closing rank for the ST category in AIIMS Guwahati in Round 1 was 54515 .

Looking at the NEET 2023 cutoff, the closing rank for the ST category in AIIMS Guwahati was 53025 in Round 1 and 54941 in the last round.

While the exact marks corresponding to these ranks fluctuate yearly, based on these ranks, you would have likely needed a score somewhere in the range of 550-580 marks or possibly slightly higher in NEET UG in recent years to have a good chance of securing a seat at AIIMS Guwahati under the ST category.

For NEET UG 2025, it's advisable to aim for a score significantly above this range to increase your chances, as competition can increase.
