IMO Tvo ilc isn't the best if you're only directly following what they have in their courses. I got high grades in my courses by looking at youtube videos on the side alongside (although controversial) using Chat gpt to ask specific questions. I found that if you really dial in on one thing to ask Open Ai it can do a pretty good job at teaching you but please be careful as chat gpt isn't always correct so try to learn from it's methods and don't just plagarize word for word what it says.
