It's good to take the Jewish public exam. I have taken the exam before, and the teacher is very professional and attentive, but it is not enough to rely on the teacher alone. I have to take the initiative to practice it myself. I remember that there was a girl in our class at that time, and the teacher asked her not to answer ∞, and she dared not simulate later. This kind of class registration is definitely ineffective, so no matter how good the teacher is, it is most important to practice it yourself.
