Hi,

Maths hons is a very renowned course of Delhi University. As such your percentage should be really good for getting admission in the colleges if DU. Now since you have not mentioned any particular college of your choice so I am going to share a general percentage requirement.

For the general category students the percentage in 12th grade must be around 97% (of best 4 subjects with maths included) fir getting admission in the best colleges of Delhi University. The definition of best here means the colleges with highest NAAC ratings. Otherwise a percentage around 95% for mediocre colleges. Or 92% around for other colleges.

Overall try to score atleast 95% to get admission in best colleges.

Goid luck!
