My favourite subject at school was English and it's still an important part of my life through my writing. My worst subject was Maths, it was something that just didn't come naturally to me. How about you?
I think any subject can be a worst or a best one depending on how it is delivered by the professor. Even if Math interests me, if the way it is taught is pretty dull, I might actually lose interest and opt to learning things by myself.
My best subject in school was English. I was so good at it and I scored well. My worst subject was Swahili. It is a language too but I never liked. Though I was good at writing it, the rules of speaking the language was tough for me.
I loved English because it helped me speak fluently, and i was also good at it. I hated maths because i wasen't good at it, i tried i always tried my best though, it wasen't easy but i went through it anyway.
I think my favorite subject changed little bit with time like when I was child I didn't liked general knowledge but when I was in 3rd standard I started to like it and became really good in arts subject that I chose arts stream in 12th and I am having bachelor of arts at current time , history is my favorite subject it was from 6th standard and worst subject in my school time was physics.
