Yes, you can apply for an MSc in a different field than your bachelor’s degree, though specific requirements will vary depending on the program and university. Many graduate programs, especially those in interdisciplinary fields, welcome students from diverse academic backgrounds. For example, a student with a Bachelor's in Electronics and Communication Engineering could apply for an MSc in Data Science or Artificial Intelligence, provided they meet the prerequisite knowledge, such as programming skills or familiarity with mathematical concepts.
However, you may need to demonstrate how your previous academic experiences or skills align with the MSc program you're applying to. Some programs might require additional coursework or certifications to fill any knowledge gaps between your undergraduate studies and the new field of interest. This ensures you are prepared for the academic rigor and specialized content of the graduate program.
It’s important to carefully research the specific requirements and eligibility criteria of the programs you are interested in. If you are passionate about transitioning into a new field, this is often a viable option, especially with the increasing trend of cross-disciplinary education.
