I am Sebastian

I study in Mxitar Sebastaci Education complex, middle school. It’s very nice here. I like middle school. We have an event coming up on December 2nd. Were having some fun during the classes Do I have any favourite teachers? not really… I like all the subjects. We have a choice where we can pick a subject where we are more interested in. The teachers are very nice too. In Mxitar Sebastaci Education complex, we do all sorts of activities. Other schools are kind boring, but this school is truly amazing.
