Intermediate and hard tutorials

Unity Learn
1

Hi,
I am new to Unity, but not to programming. I was very interested in the scripting tutorials and they seemed perfect. Unfortunately, I didn’t find the intermediate or hard tutorials, or even some areas where in grey. Are there any tutorials with a higher level than beginner or should i wait for that?
Note: Thank you so much for the amazing work you have done, Unity and this great community!
