You're paying for the course and putting in the time.
You have the right to get as much from the teacher/prof
as you can. Here is how to get the most from your prof.

1. Shop for the best teacher/prof. Find out from your
student union or from other students who the best ones
are.

2. Get to know your teacher/prof. If the prof/teacher
makes their office hours known, visit them before taking
the class and several times during the class. Get to
know them. If the teacher/prof does not welcome office
visits, don't bother them; get a different teacher/prof if
possible. Find a physics tutor if you need one.

3. Important information and hints are usually given out
on the first and last class, and during the first and last
10 minutes of each class. So be punctual, stay to the
end, show up for every session.

4. Ask questions during class. There are no bad
questions; there are bad teacher/profs. If the teacher
/prof does not welcome questions during class, find a
better one. Most teacher/profs need feedback on how
they are communicating or on their pace. If something
is not clear they need to know. you are
paying for the course, one way or another; it is your
right to get as much from the teacher/prof as you can.

5. Pay attention, look and act like a professional.
Nobody respects a clown or a pest.
