Hello, Luke! At school sometimes it's hard, sometimes easy! When you do not understand the topic, it's hard to learn. But when you digest and understand the topic, the teaching is only for joy! But you need to learn, you will find a good job and be in the circle of friends. But you will be a grammatical! Teaching is light, and not the teaching of darkness!
But study is interesting, and not just boring! It is necessary to love study!
