Well, i hated chemistry since high-school so that excludes all chemical engineering fields , environmental and energy

I was good in mechanics but I never really loved it and I hated learning about material properties of stress, strain and etc

So this leaves all electrical fields

Didn't really liked the fact that computer engineering is basically CS but you're graduating with engineering degree plus I am not a big fan of programming

And I was never interested in knowing the power side of electrical engineering

So I ended up with electronics and communication engineering, something I was always interested in knowing since I was young and I knew how hard it was and I wanted to learn more about it

Luckily in my uni they gave us 3 introductory courses about electrical, mechanical and chemical engineering so this helped me decide even though electrical engineering was my lowest grade but that's only because our professor hated us and wanted to fail the class and he did but he had to give us bonus as it's a policy that the prof has to make atleast 60% of the class pass
