Hello, 

As per your requirement, i would say that as mentioned above, you have got 180 matks and you want pharm d course in tn state. As per your marks, it may be possible to get a government college- 

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

Cut off varies evert year as per your reservation category and no. Of students applying for the same. 

Or else, you can get admission with low cut off through management quota also.

Good luck
