India

With 453 NEET scores, it is exceedingly difficult to find an institution that offers MBBS programs for students in the general category.Candidate must have earned a minimum cumulative grade point average of 45% in all subjects in class 12 exams administered by an accredited board.A marginal score of 480+ will enable you to surpass the State quota.

Yes, you can enroll in a veterinary programme if your EAMCET rank is 32000. A reputable college will admit you. Any score between 10,000 and 25,000 on the TS EAMCET exam is thought to be good, and students who fall within this range have a very strong chance of getting into the best universities. 

You need to know there are 15% seats reserved for all India Quota and the rest for state quota. So I would advise you that a score of 350+ can be safe bet.

Better keep this college in choice and also try for other institutes for your safety.

Some of the colleges are :-

1.CIPET Lucknow - Central Institute of Petrochemicals Engineering and Technology, Lucknow.

2.Amity Law School, Lucknow

3.Amity University, Lucknow Campus

4.English and Foreign Languages University, Lucknow Campus

5.Faculty of Architecture, Dr APJ Abdul Kalam Technical University, Lucknow

6.Institute of Tourism Studies, University of Lucknow, Lucknow

7.AIBS Noida - Amity International Business School, Noida

GUJCET has been made compulsory for admissions in courses like Engineering, Pharmacy, Diploma, and several Undergraduate courses. 

So, yes for government colleges you need to.

No, you will not get, you have to score approximately 500.

You can give the entrance exam of Karnataka only if you know the basic language of Karnataka. The mother language is required. Ofcourse you can give even any Maharashtrian can give the exam but knowledge is required.

You did not provide gender, state rank, domicile, etc., so it is difficult to predict with accuracy the college. According to me, you have a lower chance of getting into government colleges for MBBS programs. But you can try these government colleges. Maybe you will get admission.

1- SRM Medical College Hospital and Research Center (SRM-MCHRC)

2- Data Meghe Institute of Medical Sciences (DMIMSU)

I feel that even though your rank is reasonable, it perhaps not sufficient for admission in a government college since preference of most students is government college as first choice.
