Hii Prerna,

If you belong to a general category and want admissions in Top Colleges in the university of Delhi for pursuing Bachelors in Sciences then you would require nearly 95+ percentage be it aggregate or best of four. Sometimes is is even as high as 98-98.75 percentage. Top colleges for pursuing Bsc are Hansraj College, Ramjas College, Sri Venakteshwara college, Hindu College, Lady Shri Ram College, Jesus Mary college, Miranda, St stephens etc. You can aim for 96-97 to ascertain your admissions in one of the top colleges. If you fall in the OBC bracket then also aim for a percentage in the rage 90-93%.

Hope it helps.

Thanks.
