Hey Sai Krishna,

Each autonomous college follow different rules and regulations. Few colleges make question paper preperation by Deemed University or any other top Private College professor. Fee colleges prepare question papers by the same faculty. The preperation of the question paper is based on the college You choose. Even about the correction few autonomous colleges calls other faculty from differeEnt colleges for the correction. In few Colleges the papers are corrected by their faculty itself. Ultimately it is entirely depended on which college you choose
