Hello, 

As per your requirement, i would say that as mentioned above you have got 288 marks and have ph category reservation of seats so you will definitely habe a lower cut off for admission.

But the colllege prefernc of yours mentioned above are all top rank and mostly demanded collegr so its quite diffcult there as you need to have atleasr 300+ marks to be on  a safer side. 

Getting a seat in government medical college is depending on many factors like studenrs to seat ratio, cut off, reservation, ranking of college, etc

Apply for state and aiq counseling and see which collegr matches your marks.

Good luck
