Hey Akshansh,

I'm sorry to say but I don't think with 82% you'll get any of the science courses in University of Delhi.

Firstly, because it's one the best universities in India and secondly, because this year according to the analysts the cut offs are expected to be higher than last year. 

Last year, Aacharya Narendra Dev College gave Botany Hons at 81 but this year it's expected to rise.

Still, don't lose hope, apply for it. I hope this helps, good luck!
