英语翻译有点忙,功课很多,周末要上兴趣班没有太多时间运动,但每天坚持跑步数学有点难,但现在有进步 

I'm a little busy, I have much homework to do, and I have to go to interest classes at the weekend.I don't have any time to do exercise,but I keep running everyday. Math is a little difficult to me, but I'm working hard on it.
再问： a little difficult to me还是for me？
再答： to me
再问： 我怎么记得for me？你确定吗？我们这是算作其平时成绩的一部分！
