At the end of the school year you will evaluate your teaching. Might be most of the time you could work smoothly.
But probably it was like a battle. In the Timothy letters, Paul also speaks about a battle. Read about this, while evaluating the year in the newest bible-study in the Timothy for Teachers series.
Every few weeks Bram de Muynck writes meditations on texts, taken from the letters of Timothy. They can be used for personal meditation. Teachers may find in these texts some help for discussing core issues during team-meetings.
