How anonymous are the anonymous feedbacks on iLearn?

So I have this unit where there are two hour practicals every week and the practicals are graded. However, the tutor for the unit is absolutely terrible. His english is very difficult to understand, and he even looks disinterested in the practicals. Once he even said that it’s not his job to teach the concepts. It appears some people have already reported him, and last practical he even asked the class who provided the feedback. I’m really worried about this unit as it has many difficult topics, and every practical I end up learning nothing. I asked a few of the people in the practical, and they said the same thing about the tutor. I couldn’t shift to other time slots due to lack of availability. In this situation, what should I do? I’m also worried about providing anonymous feedback as last class he even asked people if they provided feedback.
