Hi

First of all you have chosen the right code i. e code 2,

This is because,

Though you are doing BSc your highest qualification with all the three subjects i. e physics chemistry and Biology/biotechnology remains your 10+2 as you don't have chemistry in your bsc

While, those who have passed 1st year of 3 year graduation with all the three subject i. e physics chemistry and Biology/Biotechnology needs to select code 5 and those who have completed BSc with at least any two of physics chemistry and Biology in their bsc need to select code 6.

For your reference,

Here's a short brief of Neet codes :-

--------) Code 1 :- code 1 is for class 12th board examination appearing students with physics, chemistry, biology and English or have have already appeared but results are awaited i. e have not been declared.

--------) Code 2 :- code 2 is for all those who have passed their 10+2/higher /senior secondary/ Indian School Certificate Examination with physics, chemistry, biology/biotechnology and English

--------) Code 3 :- code 3 says it is for those passed their intermediate / pre- degree examination  with physics, chemistry, biology/biotechnology and English ,your physics, chemistry and biology/biotechnology should also contain practical exam.

--------) Code 4 :- pre - medical degree with Physics, chemistry and biology/biotechnology after passing hsc i. e 10+2 or puc or equivalent.

--------) Code 5 :- code 5 is for all those who have passed  1 st year 3 year graduation with all the three of  Physics, chemistry and biology/biotechnology

--------) Code 6 :- code 6 is for all those students who have passed  BSc  with at least any two of following subjects :-

>>>>Physics,

>>>>chemistry ,

>>>>biology/biotechnology

--------) Code 7 :- code 7 is for those who have passed their examination from foreign board which is equivalent of Indian 10+2 board.

Secondly,

You don't need to worry about what other people are saying as you have chosen the right code. Moreover, your qualification code has nothing to do with your eligibility . You qualification code is neither written on your admit card nor on your results on anywhere.

The qualification code during form filling is just to know your current status:-

--------) whether you are 12th appearing

--------) already passed

--------) type of board i. e 10+2/higher /senior secondary/ Indian School Certificate Examination or intermediate / pre- degree examination

--------) if you are doing any course is it  bsc with PCB or any other

--------) or after 12th you have even passed your bsc.

--------) have studied from a foreign board.

As,

You are doing bsc  , you wouldn't have your 12th T. C as it's get submitted during admission in bsc, so now during mbbs admission you can submit your bsc T. C . I personally had few of my friends who instead of taking drop, they were enrolled in bsc but later on qualified neet and got into mbbs and faced no problem with college t. C .

Thank you
