The eligibility criteria for the M.C.A. (Master of Computer Applications) degree at South Travancore Hindu College require candidates to have a bachelor's degree in computer science, information technology, or a related field from a recognized university. Additionally, applicants must have a minimum aggregate score of 50% in their undergraduate studies. Candidates who have completed a bachelor's degree in a non-computer science field may also be considered, provided they have studied mathematics as a subject in their undergraduate program. It is important for applicants to note that meeting the eligibility criteria does not guarantee admission, as the selection process may also include an entrance examination and/or a personal interview.
