There are going to be at least a handful of classes in college where you are going to feel overwhelmed, down, and frustrated and nervous about passing. It's normal and you have to realize its part of the college experience and good training for life when things get overwhelming.
You may get a lot of the typical advice like set certain hours during the week just to focus on classes, etc. which may be important; but I have found more importantly in school and a career, that just showing up and being present is 70% of success. The other 30% is some luck and some hard work. You would be surprised at the number of people that don't even show up which eliminates a lot of competition. Do every assignment to your best ability (even if you know its not 100 percent correct), show up and put in the effort as best as you can, and just last and survive through the final. Its almost a guaranteed formula to pass and put that class behind you and move on.
