Grant Medical College Mumbai — one of India's most storied government hospitals — allotted 38 seats in Round 1 through the All India Quota. Only 12 candidates reported. 25 ghosted. Of those who left, four moved to AIIMS Deogarh, two to BJ Medical College Ahmedabad, and one each to AIIMS Raipur, BHU Varanasi, and KGMU Lucknow. By Round 3, Grant had 48 students — more than it started with — because 12 candidates upgraded in from Nagpur, Indore, and Bhopal. The same college that top-rank AIQ candidates abandoned became the destination for mid-rank candidates upgrading from elsewhere. That is AIQ: a national chessboard where every candidate is simultaneously playing against every other, and the same college can be a transit stop for some and a destination for others.

The structural difference between AIQ and state quota
Every government MBBS college in India participates in two parallel counselling systems. The All India Quota covers 15% of seats at each college and is counselled centrally by MCC. Any NEET-qualified candidate from any state can compete for these seats — domicile does not matter. The state quota covers the remaining 85% of seats at each college and is counselled by the respective state authority. Domicile is required. A candidate without domicile in Maharashtra cannot access Grant Medical College Mumbai's state quota, but can compete for its AIQ seats through MCC.
AIQ (All India Quota): 15% of government MBBS seats at each college. Open to all states. Counselled by MCC.
State quota: 85% of government MBBS seats. Domicile-restricted. Counselled by state authority.
Central institutions (AIIMS, JIPMER, PGIMER, etc.): 100% seats under MCC/INI-CET, no state quota.

The practical consequence is that a candidate's effective options depend entirely on their state of domicile. A candidate from Karnataka can access the full state quota of Karnataka government colleges — the 85% — plus the AIQ 15% of every government college in India. A candidate from a small northeastern state with few government colleges may find that AIQ is their primary route to a government MBBS seat in a major city.
Why AIQ behavior differs so sharply from state quota
The ghost rates in AIQ at top-tier government colleges are consistently high. This is not accidental. A candidate who gets Grant Medical College Mumbai via AIQ in Round 1 typically has a national rank strong enough to get AIIMS Nagpur, AIIMS Bhubaneswar, or other AIIMS-tier institutions in subsequent rounds. They leave. The 65.8% ghost rate at Grant in Round 1 via AIQ is a documented signal of this behavior: AIQ attracts national-caliber candidates who are using it as a hedging round, not a commitment round.
State quota behavior is different. Domicile-eligible candidates who receive a state quota seat at a college in their home state are competing in a smaller pool. The best available seat in their state may genuinely be their best option nationally, and their commitment rates reflect this. For example, Karnataka's government medical colleges via the KEA state quota process show significantly different retention patterns than those same colleges' AIQ seats through MCC. The same physical seat, different competitive dynamics.
The mid-rank reality: AIQ as the entry point
At ranks where government college access via state quota requires domicile in a well-served state — Maharashtra, Tamil Nadu, Karnataka, Uttar Pradesh — candidates from states with fewer government colleges find that AIQ is their only route to a government MBBS seat at a competitive college. For a candidate from Jharkhand, Chhattisgarh, or a northeastern state with limited government MBBS infrastructure, the 15% AIQ pool at colleges in larger states can represent more options than their entire home-state quota combined.
The reverse is also true. For a candidate domiciled in Maharashtra who qualifies for the state quota of government colleges there, AIQ is often less relevant — the 85% state pool gives them more options within their preferred geography than the national AIQ pool would. The same All India Rank translates to very different effective option sets depending entirely on domicile.
Grant Medical College Mumbai (MCC code 200219): 38 AIQ seats R1 → 12 reported → 25 ghosted (65.8% ghost rate). By R3: 48 total students — 20 upgraded in from Nagpur, Indore, and Bhopal-area colleges.
At high-rank colleges: AIQ ghost rates are high because top-rank candidates have national AIIMS-tier options.
At mid-rank colleges: AIQ is often the entry point for non-domicile candidates who have no other access route.

Running both systems simultaneously
Most states permit candidates to participate in MCC AIQ counselling and state counselling in parallel, up until the point of joining. The timing is where candidates are caught: MCC round deadlines and state counselling deadlines often overlap, and a deposit paid in one system may need to be forfeited when accepting a seat in the other. The total deposit forfeiture across MCC UG 2025 was substantial — 2,847 candidates forfeited deposits across all rounds. This is not always an error; for many candidates, it is the planned cost of keeping multiple paths open until the best allotment arrives.
Understanding which path — AIQ or state quota — carries more options at a given rank requires knowing both the national rank and the domicile state simultaneously. The same rank of 15,000 puts a candidate in a very different position if they are domiciled in Tamil Nadu versus Meghalaya, because the 85% state quota in Tamil Nadu government colleges is available in the first case and unavailable in the second.
