We cannot predict your percentile score with your marks or your percentage as the percentile scores were calculated after normalisation of your marks, various factors were kept in mind such as the difficulty level of your paper as compared to the other papers. Your percentile scores are still available on the NTA website and you can check out the following link to see your percentile scores-
