Hi

You have not mentioned the category you belong to, so I am  assuming  you from general category

It's quite difficult to predict that whether you will get  seat or not as  cut off marks for medical colleges keeps changing every year  depending upon various factors like  number of students that appeared in the exam, kind of marks obtained by them , toughness level of the examination etc.

But when we go through previous data then it suggests that with 506 marks   you hold  low chance to get a seat in APOLLO INST OF MED SCI, HYDERABAD

For example,
In Neet 2019, 560 marks for general category was  the lowest marksthat got a govt seat in APOLLO INST OF MED SCI, HYDERABAD   under Telangana State quota

But yes you have chances for Government quota seat in following private medical colleges under Telangana state quota:-

*AYAAN INSTITUTE OF MEDICAL SCIENCES

*DR PATNAM MAHENDER REDDY INST OF MED SCI, CHEVELLA

Above prediction is on the basis of past year data  but  cutoff keeps changing every year due to many factors as mentioned earlier, so to have a clear picture of the colleges in which you have chances and
