hey mehtab 

kindly mention your homestate where you want to get admhissions . at this percentage it is quite tough for you to get admissions on merit besed but you can surely try for colleges  taking admissions on entranced base .you can also join open courses from ignou or du sol . also try to look for good private colleges nearby as bsc doesnot put huge diffence between different colleges in term of quality of educaion 

best wishes
