my daily routine

I fell asleep late in the night, so I overslept and got late for school. ButFortunately, my teachers are very kind and understanding people. The population of my class is very few small, therefore teachers meets  get to know every student. I caarefully listening to my lessons, because i love learning and i want to intellectual accumulation become smarter/obtain as much knowledge as possible. I want improve my English and take the exam. I'll take it next year but my English is so limited. I am open to all proposals and advices. Anyway what was I saying?  While I was heading to school, I baught a sesame ring from the bakery. It generally takes me thirteen minutes to walk to the metro/underground station. The metro takes about 25 minutes. Then I walk 10 minutes to reach the school. Can I stop writing for now? I'll continue later.
