Hi aspirant

While filling your application first you should know under which category your caste will come like st,sc,obc,bc-a,bc-b so you can choose them . You will get reservation particular to that category . And jee advance will be more deeper than jee mains so you should be mor careful about filling application and if you fill wrong caste your original reservation will be wasted . So go through the internet about your caste and select that category.
