Best course to study these days?

It depends on your interests, but if you’re looking at the AI era, I’d focus on Computer Science, Data Science, Artificial Intelligence, Machine Learning, or Software Engineering. More important than the degree itself is building practical skills in programming (especially Python), AI tools, data analysis, and problem-solving. AI is changing many industries, so combining AI knowledge with another field (healthcare, finance, education, design, etc.) can be even more valuable than studying AI alone.
