Is it possible to switch from an Electronics and Communication background to a Data Science master's program abroad?

Yes, switching from an Electronics and Communication background to a Data Science master's abroad is possible, especially since you have a BTech in Computer Science.

Universities typically look for a strong foundation in mathematics and programming. Your background should include relevant coursework in areas like calculus, linear algebra, statistics, and programming languages such as Python or R.

Some programs may have specific prerequisites or require you to demonstrate your quantitative and analytical skills through your academic record or statement of purpose. English language proficiency (like IELTS) is usually required.
