Yes ,you can get admission with 88.6%, but it depends upon the course which u want to pursue. I am providing the link of previous year cutoffs of various DU colleges, check for the course which you want to do. You may not get the top 5 colleges ( topmost branches ) but there are a lot of other options.
Hope this helps !
