You can modify your registered course participation during NUCAT registration through to its closing date. To change your selected course visit the NUCAT authorities and explain your reasons with your preferred new course. After submitting the registration form you can request changes to your preferred course yet you must contact NUCAT authorities who need proper information for the modifications. 

Begin by understanding the NUCAT syllabus and exam pattern. Collect study materials, including textbooks, reference guides, and previous years' question papers. Create a study schedule that covers all subjects and dedicates sufficient time for revision. Set realistic goals, take regular breaks, and reward yourself for achieving milestones. Stay connected with peers or mentors who can guide and encourage you. Avoid stress by maintaining a balanced routine with proper sleep and exercise.

No, the NUCAT answer key is not the same for all sets of question papers. The exam usually has multiple sets or codes to maintain fairness and prevent malpractice. Each set has a unique arrangement of questions, so the university releases separate answer keys for each set. Candidates must ensure they download the answer key that corresponds to the set or code of their question paper to accurately verify their answers.

You can download the NUCAT answer key from the official Nitte University website. Typically, the answer key is made available under the "Examinations" or "Admissions" section. Visit the website, navigate to the relevant page, and look for the notification or link related to the NUCAT answer key. Ensure you download the answer key corresponding to your question paper set or code. If you face any difficulties, contact the university's helpline for assistance.
