You have not mentioned about your reservation category,
Considering the previous years Cutoff the students of general category secured seat in MGM kishan ganj with 691- 119 marks and in 2017 with 697- 131 marks,
As you seem to have chances of getting seat in that college, so I suggest you not to loose hope and keep going,
