If you are struggling with the material, be aware that you have options:
(1) Struggle a bit. Part of the learning process is the internal struggle
of trying to understand how all of the pieces fit together. It can
be frustrating, but it can also be rewarding. If you make progress,
however slow, then it is time well spent.
If you feel that your time is not productive, then you should talk to me,
or other students, about how you can make better use of your study time.
(2)
Visit my office hours. It is part of my job to be available to help
you understand the material. There is not enough time in the classroom to get
everything across, and you are not expected to do it all on your own.
(3) Find alternate instructional material online. Different people have
different styles, and while you might have found my way of discussing something
to be confusing, there may be someone else out there who can discuss it in
a away that makes sense to you. There are a number of free text books,
lessons, and video lectures available online. Feel free to ask me about other sources.
(4) Talk to your fellow students who are taking or who have taken the class.
Learning is a social activity; you are not expected to do it all on your own.
(5) If after availing yourself of the above options, you still find that you are struggling regularly to understand the material, find a regular tutor.
If you are in this situation, you will likely have to spend significant extra
time on the material to ensure a passing grade.
