Hi! Do you know any resume of grammar for A2/B1 level in English?

Languages at the school I am learning two languages at school now (English and German). We have English classes three times a week (one class is 45 minutes) and twice a week we have German classes. But basically, I didn´t learn anything in school classes. I am learning English outside of school with a tutor, so everything, what I know in English taught that tutor. German, I am learning at home myself. In school classes, we usually spend 20 minutes for excuses like: "Ms. teacher, I am so sorry, but I forget my homework"." Next 15 minutes, we usually write a test, the last 10 minutes we usually learn some grammar. Normally we don´t speak at classes. What are your experiences about language classes at the school?
