Your admission to the BA (Hons) Political Science programme offered in any of the college affiliated to the Delhi University entirely depends upon the score and percentile obtained by you in the Common University Entrance Test (CUET UG) conducted by the NTA. As you have obtained 584 out of 800 in the CUET UG, it will not give you guarantee to get admission in the Delhi University , as the cutoffs may vary every year depending upon number of factors such as the college, course, number of candidates who have applied for admission in the DU, competition in the entrance exam, candidate's category, etc.
