School

I’m glad because I’m going to start to work ("to work" isn't wrong, but to me it sounds more natural to omit the "to", in which case "work" is a noun.) in a school tomorrow. I’m going to take a train for going to job to work. I’m expectant ("expectant" sounds unnatural.  Perhaps "excited"?  "looking forward to it" is probably the most natural phrase, but you used that immediately in the next sentence.). I look forward to knowing the children and teachers. I’m going to pass spend all day at school because timetable the schedule is: 9h.-17h. (We usually use the 12-hour clock in the English speaking world.) I hope to like (a little more natural: "I hope I like") this school.
