No, your percentage is too low so you won't get any seat for B.Sc(Hons.) Try for some other courses. The cutoff is hardly 75 so your percentage is too low. You don't even have 1st division so not a chance. Nowadays, 60% for honors is mandatory, so I recommend you to give improvement of 12th and score high percentage so that you can get a seat in some good college and with your own subject selection or go for entrance test so that the percentage doesn't matter.
Good Luck.
