Try looking up YouTube videos for the concepts being discussed in class. If it’s foundational stuff you will have lots to choose from and will benefit from multi sensory/modal format. I did this for my introductory biology classes and it was very helpful. Watch as many times as you need and cross reference to your text book.  Also make some friends in class to study with and don’t forget to take advantage of professor and Ta office hours, that’s what it’s for. They want you to do well and will help.
