用usedto语法介绍自己写一篇英语作文

When I was in primary school,I used to go school at 8:00.But while I went to middle school,I need to get up earlier than before.Because my teacher asked me to go to school at7:30.After going to school,my classmates and I need to do a lot of reading before our first class is beginning.
Another important difference is I need to learn physics and chemistry now.These two courses are really very hard for me.But I believe,"No pain,no gain".I can learn it as good as my classmates.
