I HATE EXAMS!!!

My exams are starting next week... I've been trying to ACTUALLY study for a while now so I hope I actually get good grades. The only subjects im afraid of are arabic, literature and Mathematics, I hate arabic bc I know NOTHING about it, ive honestly only been passing the class bc the teacher is really generous (bless her), i hate literature bc man i dont care about how poems were written like 1000 years ago why do i need to know and WHY ARE THERE SO MANY TYPES OF POEMS CREATED DURING THAT TIME??? anyway, im scared of math but im not rlly bad at it, i love math! except functions. I just dont understand how they work... not like the basic ones like f(x) = x + 1 or something but like the more advanced ones. Especially the graphics. I cannot read them at all. But my classmates say theyre the easiest and its really discouraging me -_- 

This was just ranting so yeah
