Deciding what classes to take is not as hard as it may sound. Figuring out what times work best with your schedule may be the tricky part. Thankfully, it has always worked out for me because all my classes have been offered throughout different times of the day.
Every semester, right before the registration period, we meet with our advisers to discuss what classes we should take during the upcoming semester. This is helpful, but my favorite method is viewing the What-If Analysis on CNU Live. All you have to do is enter your entry year, major and minor (if any). After entering this information, you will be directed to a page that displays all the requirements needed to graduate. It will list the courses you need to complete and if they have been completed already or not.
This is an organized way of viewing what classes you are required to take to graduate. I did not use this my freshman year, so I ended up taking a few classes that I did not even need. It is extremely helpful and may save you a lot of time.
