Hello Roshitha,

As, you have mentioned that you belong to ST category and your score is 330.

Although it is very difficult to predict the cutoff as it depends on various factors And the cutoff has also not yet been released.

However ,by  looking at the cutoff of the past few years and observing the trend, I can say that you may not have a chance of getting a seat in a government college.

Still, you can apply for private colleges in India, or can try once again for better marks next year.

I am providing you link through which you can check the cutoff of the previous years in govt. colleges

Or, you can also use the rank predictor tool for estimated rank for your marks

Hope this will help you.

Good Luck !
