Alright. So when you go to the application form, in the 7th field "candidate is a domicile of" you will select Maharashtra, right?
Under reservation, select that category, of which you are eligible for reservation (caste wise, or religion wise, or defence, or income).
Under educational details, you will select Outside Maharashtra. Accordingly center options will be displayed.
Under the 15th field that asks for "I want to claim exemption under, additional weightage" and so on, select only those that you are eligible for.
Which field are you facing problem in?
