You don’t have to just listen.
“Sir, I don’t understand why we used this equation here.”
“Let’s go back one step. Look at what’s rotating.”
Ask your question. Stop the teacher. Ask them to explain it another way.

Tell us what you need and we’ll open a new batch to suit it.
A teacher who doesn’t fully own a chapter teaches it half-convincingly, and you absorb the hesitation.
Learn it from someone who owns it, and you absorb their certainty instead.Usually taken before this one
