CUCET MTech Material Science Syllabus

Central Universities Common Entrance Test commonly known as CUCET is conducted for admission to Integrated / Under-graduate, Post-graduate and Research Programmes in Centres Universities. Ten Central Universities (Bihar, Gujarat, Jammu, Jharkhand, Kashmir, Kerala, Orissa, Punjab, Rajasthan and Tamil Nadu) have joined hands and institutionalised "Central Universities Common Entrance Test" (CUCET). Thus, one single application and entrance test (CUCET) provides opportunities for admission in Ten Central Universities located nationwide.
