Hello Vijju,

AP EAMCET is a state level exam that is conducted by Andhra Pradesh authorities for admission to various undergraduate courses offered by institutes of Andhra Pradesh. As for your question, you can do it if you haven't yet submitted the application form because AP EAMCET does not provide any correction window. You can also try to contact the authorities on the official email id or phone no to ask for further instructions.

On another note, unless you are eligible for scholarships under the family income and have mentioned it wrong, there is no need for changing the income range.
