I can score 550 mark in neet what would be my rank and college in up? category general

Dear Raj, in 2018 with a score of atleast 550, under General Category seats were given to

Sarojini Naidu Medical College
Maharani Laxmi Bai Medical College
BabaRaghav Das Medical College
UP Rural Institute of Medical Sciences and Research
Dr. Ram Manohar Lohiya Medical College
Govt. Medical College, Ambedkarnagar
Govt. Medical College, Kannauj
Govt. Medical College, Jalaun
Govt. Medical College, Azangarh
Govt. Medical College, Sahranpur.

Going by the previous trends with a score of atleast 550 and above, you can certainly get a good Govt. Medical college. Having said that, Cut off depends on various factors like No. of seats available, no. of candidates appearing for the exam, difficulty of the exam and top NEET score.
