The most difficult subjects

The subjects that I find the most difficult are spanish and latin. I study in the spanish advanced level and I don't like it because I study a lot and I put a lot of efford in the subject but I'm not good at it. Also I don't like the books they give us to read, I wouldn't choose them.
The problem with latin is that there are way to many ways to declinate words and you have to know all of them and when and when not to use them. The verbs are the same, there are 5 conjugations and each one works a different way. I like latin and I will continue to do it next year but it's not an easy language.
