Hello Aakash
115 out of 200 isn't a bad score but rank are subjected to change as they depend upon many factors like number of applicants fill the form, number of applicants finally appeared in the exam, number of questions asked in the exam, difficulty level of the exam, performance of the candidate, previous year's cut offs trends. As the results and cut offs aren't out yet ye can't be certain about your rank but you may predict your rank with the help of career360 MU OET rank predictor and can check previous years opening and closing rank for different streams.
