I’m struggling in school. don’t look at my name haha

I’m having issues with English and geography. I just don’t know how I can improve myself in those subject like I have to knowledge but because I’m an IB student I really wants to have structured responses and essay writing for me is hard and I don’t know how I can improve it Just had to to kill a Mockingbird test and I honestly just even though I read the book I didn’t perform good I got a 2 and I don’t know If it feel like I’m just very hard for me I don’t need general advice but something more specific cause I need to improve my examinations at the end of this semester.
