Nothing in the world is easy or hard. It depends on perception and interest. One find maths very interesting and easy while one finds economics the easiest. Interest would matter. You should rather figure out what you want to do in life than see easy or hard. If you are fascinated and inspired by something, it’s easy automatically.Your own interest makes something easier or difficult. Both on par with syllabus and difficulty level.
Frankly, neither science is easy nor commerce nor arts nor a shortcut to Diploma is easy. When you step into high school life does not becomes easy and equally when you step in Diploma College life does not becomes easy.Indeed! science is more calculative and competitive but at the same time commerce or arts is also not easy. You get economics, accountancy, business studies …these subjects are very scoring but you need to understand it carefully.Same thing is there in science,if you love maths and science subjects, definitely, it will prove very scoring. It same as science is also very conceptual.
See each and everything is easy, if you work hard on it. Same applies to arts, commerce or science. I would only suggest you that first look for your interest, then present and future opportunities in that field and then make choice for commerce or science.
In nutshell, where there is will there is a way.If your keen interest would be there nothing would be difficult.But always remember,
“Standing at the foot boys, looking at the sky. How can you get up boys, if you never try?”
