===============
Would you check thesentences? Which ones should I use?

Answer 1

2 and 3 are best. 1 could be to write down the teacher's ideas, not your impression of them. 4 is just rather clumsy and not quite clear.

#3 does not need the word "do". "Write down how you feel about your favorite teacher."
