I don't know what to do. I'm one of those who most people would hate (though I don't think my friends hate me), because I always get high grades without too much effort while almost everyone else is struggling and just hoping to pass.

I do help them when they ask, though sometimes it wears me out, or I feel too lazy to really do a good job teaching them. I feel selfish when I do this though. Sometimes I try to be selfless and have the mentality that it doesn't matter if I fail as long as they do okay, but when it comes down to it, I end up looking out for myself over them and I come out on top.

Anyway, a lot of times they do understand better when I explain to them, but when the test comes, I fail them. Even those who understand the lesson get tripped up when it comes to the exams. I just learned today that another friend (who I don't teach) failed his exam. I had seen him studying and felt that he did get the lesson, but.. well, it's not an uncommon story.

I used to like math (yeah, I usually like things / people, i.e. teachers, a lot of others hate), but I'm having mixed feelings. I don't know how to help them, or if I can even be committed enough to help them. It's so sad. It sucks.
