I score 406/1250 in cuet can I get admission in this college for bsc maths

Mata Sundri College for Women is part of Delhi University, and for B.Sc. (Hons.) Mathematics, the cutoffs are very high:

• 85-95 percentile for General

• 75-85 percentile for OBC

Your score of 406/1250 is quite low compared to these cutoffs. Even in later CSAS rounds, the cutoffs for this course at DU colleges rarely drop below 650-700 marks.
