Hello,

If you are asking about SCB (State/Central Board) quota under AIIMS or IISER through NEET , then please note:

For SCB channel in IISER , NEET score is not accepted . IISER accepts applications through:  IISER Aptitude Test (IAT), KVPY (until 2022), JEE Advanced, SCB channel (based on class 12 marks + IISER Aptitude Test).

If you are asking about NEET admission to MBBS/BDS in general and mean SCB as State Counselling Board , then:

  • For Government MBBS colleges , if you are from SC category , you usually need around 400 to 470+ marks in NEET (varies by state and college).

  • For Private colleges , cutoffs are lower, sometimes even around 250–350 marks for SC category.

Hope it helps !
