I am sorry but I think there is no chance.

Don't worry, you are having 320 marks in JEE main, tou can try many private good colleges in south india, who takes only JEE main marks, like bannari amman college and many more!

Maybe. Are you from SC/ST or another category?

It's all upto you! If you feel that you can do better, then go for it!
But keep in mind that JEE Mains rank is only important when you have a pretty much good rank! I have two of my seniors who dropped a year and performed really well compared to last years' result and are sure to get admitted to NITs.
All the best!
