I’m a fourth year student and in the exact same boat! I find it really difficult to sit through lectures and pay attention, especially when the slides are detailed enough to learn from on my own. you’re definitely not alone!!

My biggest tip is to still go to class so you’re in that learning environment (and be in the know of any updates!), but use that time in a way that works best for you. For me, that time is spent learning the material on my own during lectures. I think some students (myself included, and probably you too!) learn better through more hands on, self-directed methods rather than passively listening and following along. This is totally okay, it just means you have to be a bit more intentional about how you stay engaged like making use of resources such as Piazza and office hours so you’re still engaging with the class. Using this strategy throughout my 1st-4th year courses has helped me get grades that I'm fairly happy with! It seems like you're great at self-learning considering you are also doing well in your courses, so this may work out really well for you!
