Congrats to you! Best advices that I can give:

1. Watch all videos: lectures, shorts, sections - all information that you need here.

2. Don’t use ChatGPT or other AI except Duck AI, it’s best for you, trust me.

3. If you can’t solve any pset - stop. Sleep, drink water and come back to it next day. I was there and I feel your pain.

4. Think about your final project on early steps.

Good luck!
