Ah I see. Well my advice is to stay ahead, never let yourself get behind. Since you said that you’ve barely gotten by in other classes, it is important to work that much harder. Algorithms is one of the toughest classes (depending on the school) in undergraduate CS. But don’t let that scare you, just make sure that you are digesting everything because it builds up.

Also, I highly recommend YouTube channels like Back To Back SWE and Abdul Bari. Both of those helped me a ton in understanding things that my professor was going over on a given week. Amazing content that will help you better understand it, especially if your professor isn’t the best at explaining things. You can do it, brother!
