In the past three years

I think my school life has changed a lot in the past three years.I used to think my school life is boring.I did many things alone.In the past three years,I has learnt to get along well with the classmates around me.I made friends with them.So I didn't feel lonely any more.The school life was always busy.And sometimes,I had some troubled problems on my study,I usually tried to solve the problems alone,not to ask others for help.As time went on,I changed.I started to ask for help.In the past three years,I has changed a lot.All of these were what I have learnt in the past three years.In a word,although my school is busy,it is also full of happiness.
