If you are going to appear for JEE-Main or JEE-Advance than you should keep in mind that you have to score above or equal to 75% in you 10+2 i.e. only 12th. So according to the data given by you you have scored 360 marks out of 500 in 10+2 according to which you have secured 72% which makes you ineligible for JEE-Main.
But note that if you have secured your position in top 20 percentile of your state board results than also you are eligible for JEE-Main.
