I don't like any IGCSEs but here you go
Additional Math (Even though it is annoying because learning theorems make all problems easy)
Chemistry (It is alright even though there is some ambiguity at times)
Computer Science (I love this topic but IGCSE made it boring. The question paper doesn't even test for the skills which are taught.)
Physics (love this one too but again IGCSE made it...)
Biology (too much theory and no clear focus. There are so many damn question about descriptive writing in the exam. Also, doing geography saved me during the exams. Almost half of the paper was concerned with the last chapter.)
Geography (too much ambiguity)
English FL (It's alright. I am somewhat bad at it but I just don't like it. I love reading though.)
